(5)

Installation  of  the  backupscript  

(easy)  

 

The  easy  installer  will  install  the  backup  script  for  you,  only  asking  for  your   backup  credentials  and  your  email  address,  any  extra  configuration  steps  will   automatically  be  applied  by  the  installer.  

 

Downloading  and  running  the  tool:  

 

First  we  need  to  download  and  run  the  tool  in  order  to  install  the  backupscript,   issue  the  following  commands:  

wget –O cloudvps-backup-installer

http://download.cloudvps.com/pub/files/scripts/backup/cloudvps-backup-installer.txt

chmod +x cloudvps-backup-installer ./cloudvps-backup-installer

 

The  menu  presented  will  not  show  all  options  that  are  available,  only  the   necessary  items  are  displayed  for  now:  

 

   

Please  select  option  1  and  select  OK.    

The  installer  will  now  try  to  install  all  required  software  (see  page  4  for  details)   and  when  it’s  finished  installing  the  software,  you’ll  be  presented  with  the   following  menu:  

(6)

   

Please  supply  the  following  details  in  the  appropriate  fields:   -­‐ Username  

-­‐ Password   -­‐ Backupserver   -­‐ Email  address    

When  done,  select  OK  and  the  script  will  start  installing  the  backupscript  on  your   server.  

 

At  the  end,  upon  finishing  installation,  the  script  will  ask  you  to  send  a  simple   installation  report  to  the  given  email  address,  please  select  the  option  you  want.   (It’s  always  a  good  idea  to  send  the  report  to  ensure  that  the  mail  function   works!)  

 

Now  the  backup  installation  is  finished!    

Note:  

In  addition,  it  checks  to  see  if  MySQL  is  installed  and  if  the  configuration  is   readable.  If  so,  the  dump  flag  will  be  set  to  “Y”  and  else  to  “N”.    

 

In  the  easy  mode  the  automatic  update  option  is  enabled  to  ensure  that  you   always  have  the  latest  backupscript  installed.  These  updates  are  checked  once  a   month  and  applied  if  yes.  This  can  be  disabled  later  via  the  configuration  editor.  

(7)

Installation  of  the  backupscript  

(advanced)

 

 

Should  you  need  more  control  over  the  installation  aspects  of  the  backupscript,   you  can  use  the  advanced  installer.  

 

Downloading  and  running  the  tool:  

 

First  we  need  to  download  and  run  the  tool  in  order  to  install  the  backupscript,   issue  the  following  commands:  

wget –O cloudvps-backup-installer

http://download.cloudvps.com/pub/files/scripts/backup/cloudvps-backup-installer.txt

chmod +x cloudvps-backup-installer ./cloudvps-backup-installer

 

The  menu  presented  will  not  show  all  options  that  are  available,  only  the   necessary  items  are  displayed  for  now:  

(8)

Please  fill  in  all  the  details,  the  only  fields  that  optionally  may  be  left  blank  are   the  MySQL  user  details,  all  other  fields  must  be  populated!  

 

When  done,  select  OK  and  the  script  will  start  installing  the  backupscript  on  your   server.  

 

At  the  end,  upon  finishing  installation,  the  script  will  ask  you  to  send  a  simple   installation  report  to  the  given  email  address,  please  select  the  option  you  want.   (it’s  always  a  good  idea  to  send  the  report  to  ensure  that  the  mail  function   works!)  

 

Now  the  backup  installation  is  finished!    

Note:  

If  you  disable  the  notification  system,    the  following  notifications  will  not  be  sent:   -­‐ Update  checks  

-­‐ Log  mails  

-­‐ Full  account  mails    

In  addition,  it  checks  to  see  if  MySQL  is  installed  and  if  the  configuration  is   readable.  If  so,  the  dump  flag  will  be  set  to  “Y”  and  else  to  “N”.  Should  it  display   “Y”  but  no  MySQL  user  details,  please  provide  the  details  in  the  appropriate  fields   or  set  it  to  “N”  manually  if  you  don’t  want  the  MySQL  backup  to  be  enabled.    

It’s  also  a  good  idea  to  leave  the  automatic  update  option  enabled  to  ensure  that   you  always  have  the  latest  backupscript  installed.  These  updates  are  checked   once  a  month  and  applied  if  yes.  Disabling  this  will  only  send  an  email  notifying   you  about  the  update  and  how  you  should  apply  it.  

(9)

Configuration  editor  

 

In  order  to  use  the  configuration  editor  you  need  to  have  the  backupscript   installed,  please  refer  to  page  5  or  7  for  the  installation  steps.  

 

The  configuration  editor  can  be  used  to  alter  some  configuration  options   regarding  your  backupscript,  like  the  retention  settings  or  the  MySQL  dump   functionality.  

 

To  edit  or  view  your  current  configuration  details,  run  the  backup  installer  and   select  option  3,  which  will  show  the  following  menu:  

 

   

Change  any  configuration  details  that  need  to  be  changed  and  select  OK.  The   settings  are  saved  immediately.  

 

Note:  

When  changing  the  email  address,  this  will  only  change  the  email  address  to   where  the  notifications  are  sent.  The  email  address  in  the  crontab  cannot  be   changed  using  the  configuration  editor  and  should  be  edited  by  hand  using  the   following  command:  

(10)

Uninstall  the  backupscript  

 

In  order  to  use  the  uninstaller  you  need  to  have  the  backupscript  installed,  please   refer  to  page  5  or  7  for  the  installation  steps.  

 

The  uninstaller  function  will  remove  the  backupscript,  its  configuration  files  and   the  logs.  

 

To  uninstall  the  script,  please  run  the  installer  and  select  option  4.    

As  a  confirmation  you’ll  be  presented  with  the  following  window:    

   

Upon  selection  Yes,  the  script  will  be  completely  uninstalled  and  any  traces  of   the  script  will  be  removed.  

 

Note:  

The  uninstaller  is  not  able  to  automatically  remove  the  installed  backup  cronjob.   In  order  to  remove  the  cronjob,  issue  the  following  command  and  remove  it   manually:  

crontab –e  

(11)

Show  quota  usage  

 

In  order  to  calculate  the  current  used  quota  you  need  to  have  the  backupscript   installed,  please  refer  to  page  5  or  7  for  the  installation  steps.  

In  addition,  quota  support  is  only  available  for  CloudVPS  and  the  former  XLS   Hosting  backupservers.  Using  your  own  backupserver  will  not  provide  any  quota   details.  

 

With  the  quota  usage  system  you  can  see  a  real  time  disk  calculation  of  your   backup  account.  It  will  log  in,  fetch  the  quota  summary  and  parse  it  into  readable   format  showing  the  results  in  a  dialog  window.  

(12)

Quota  calculator  

 

The  quota  calculator  is  a  good  method  to  find  out  what  the  maximum  retention  is   you  can  setup  during  the  setup  process.  

 

Run  the  backup  installer  and  select  option  7,  which  will  present  the  following   menu:  

 

   

Please  enter  the  retention  you  wish  and  it  will  calculate  the  needed  space  on  the   backupserver,  in  this  example  we  will  suggest  2  weeks  and  2  months  extra   retention,  which  in  turn  results:  

 

   

This  way  you  can  adjust  your  retention  and/or  account  size  according  to  your   needs.  

 

Note:  

The  calculation  made  via  this  tool  is  a  rough  estimate  of  the  space  needed  based   on  the  given  retention  and  the  harddisk  space  the  server  currently  has  in  use.   We  cannot  be  held  responsible  for  any  miscalculations  made  by  this  tool.    

(13)

Update  backupscript  

 

This  section  applies  to  the  part  where  you  already  have  the  2.0  script  or  higher   installed  (via  this  tool).  For  upgrading  instructions  regarding  previous  scripts,  see   page  14.  

 

We  often  post  updates  for  the  backupscript  which  will  contain  new  functions  or   corrects  bugs  and  software  issues.  

The  update  functionality  will  check  for  updates  and  will  ask  you  to  install  them   when  available.  

 

Please  run  the  backup  installer  and  select  option  5.  You  will  be  asked  if  it  should   search  for  updates  and  if  it  finds  an  update  it  will  show  the  following  window:    

   

Please  select  Yes  and  let  the  installer  update  the  backupscript  for  you.    

If  you  have  the  auto  update  function  enabled  then  you  should  not  need  to  run   this  part  of  the  installer.  The  script  will  search  for  updates  by  itself  once  a  month   and  install  them  should  it  find  any.  

 

Note:  

The  backup  installer  also  checks  for  self-­‐updates  every  time  you  run  the  installer   to  make  sure  you  have  the  latest  installer  active  and  running.  The  update  

dialogue  is  the  same  as  for  the  backupscript.  

(14)

Upgrade  from  previous  versions  

 

This  section  applies  to  users  who  are  using  the  backupscripts  prior  to  version  2.  For   upgrading  instructions  regarding  the  2.X  backupscript,  please  refer  to  page  13.    

 If  you  have  the  old  XLS  Backupscript  installed  you  should  upgrade  using  the  new   CloudVPS  backup  installer,  there  are  some  requirements  that  need  to  be  met:    

Supported  versions  for  upgrade:   -­‐ XLS  Backup  version  1.4   -­‐ XLS  Backup  version  1.5   -­‐ XLS  Backup  version  1.6     Unsupported  versions:   -­‐ XLS  Backup  version  1.3   -­‐ XLS  Backup  version  1.2   -­‐ XLS  Backup  version  1.1  

-­‐ The  upgraded  version  of  the  XLS  Backupscript  where  the  configuration   options  are  in  the  backupscript  itself.  

-­‐ The  initial  release  of  the  XLS  Backupscript.    

Installation  instructions  for  the  unsupported  versions:  

Remove  any  old  backup  files,  mostly  the  following  command  is  enough:   rm /usr/local/bin/xlsbackup

Also  remove  the  cronjob  with  the  following  command:   crontab –e

When  done,  please  refer  to  page  5  and  follow  the  installation  instructions.    

Upgrade  instructions  for  supported  versions:  

First  we  need  to  download  and  run  the  tool  in  order  to  upgrade  the  backupscript,   issue  the  following  commands:  

wget –O cloudvps-backup-installer

http://download.cloudvps.com/pub/files/scripts/backup/cloudvps-backup-installer.txt

chmod +x cloudvps-backup-installer ./cloudvps-backup-installer

 

Please  select  “Update  backupscript”  from  the  menu.  The  installer  will  first  check   if  all  required  software  is  present  and  installs  it  where  necessary.  

 

If  all  necessary  software  is  present  the  script  will  ask  you  if  it  should  check  for   updates,  please  select  “Yes”.  When  the  script  found  the  update  please  let  the   script  upgrade  the  backupscript  by  selecting  “Yes”.  

 

(15)

Clear  old  backup  logfiles  

 

In  order  to  use  the  clear  function  you  need  to  have  the  backupscript  installed,   please  refer  to  page  5  or  7  for  the  installation  steps.  

 

The  backupscript  produces  logfiles  every  time  the  backup  starts.  This  log   contains  information  about  the  files  that  where  transferred  and/or  log  errors   during  the  backup  session.  

 

These  logfiles  can  take  up  a  good  amount  of  space  (certainly  when  running  for   months)  and  can  be  cleared  automatically  to  gain  extra  space.  

 

Should  you  wish  to  backup  these  logfiles  first,  the  logs  reside  in   /var/log/backups/  

 

To  clear  the  logfiles,  please  run  the  installer  and  select  option  8,  you  will  be   presented  with  the  following  question:  

 

   

In  this  example  it  will  delete  20  logfiles  and  clear  up  9.7  Mb  of  space.    

Select  “Yes”  to  start  the  removal  process  and  should  be  finished  within  a  couple   of  seconds  or  select  “No”  if  you  don’t  want  to  clear  the  old  logs.  

(16)

Testing  your  configuration  

 

In  order  to  use  the  test  suite  you  need  to  have  the  backupscript  installed,  please   refer  to  page  5  or  7  for  the  installation  steps.  

 

The  test  suite  is  a  handy  tool  to  check  if  all  configured  backup  options  are   working  as  supposed.  

 

The  test  consists  of:    

-­‐ Checking  SSH  connectivity  with  the  backupserver  using  the  SSH  key   supplied  in  the  configfile  

-­‐ Checking  the  MySQL  dump  functionality  (if  MySQL  dumps  are  enabled)   -­‐ Check  to  see  if  the  retention  settings  will  fit  the  backup  account  (only  for  

CloudVPS  and  former  XLS  Hosting  backupservers)    

Running  the  test  will  result  in  the  window  shown  below:    

   

In  this  case  the  SSH  connection  was  not  successfully  established  with  the  remote   server  and  quota  support  is  not  available  (own  machine)  and  MySQL  dumps  are   not  enabled,  therefore  has  not  been  tested.  

 

Based  on  the  error  you  may  be  able  to  correct  the  problem  better,  because  you   can  see  clearly  why  it  fails  to  run.  

(17)

Running  the  backup  manually  

 

Should  you  wish  to  run  the  backup  manually  you  can  do  so  via  2  ways:    

-­‐ Run  the  backup  installer  and  select  option  11.  

-­‐ Execute  the  following  command  via  the  commandline:   /usr/local/bin/cloudvpsbackup  

 

The  output  is  exactly  the  same  as  you  receive  via  email  and  should  only  be  used   if  you  really  need  to  run  the  backup  an  extra  round.  

(18)

Recovering  data  from  backup  

 

In  order  to  use  the  recovery  suite  you  need  to  have  the  backupscript  installed,   please  refer  to  page  5  or  7  for  the  installation  steps.  

 

The  most  important  function  of  having  backups  is  being  able  to  restore  the  data   available  on  the  backupserver  in  case  of  emergencies.  

 

The  installer  has  a  simple  restore  option  built-­‐in  which  is  able  to  restore  files,   folders  and  MySQL  database  dumps.  

 

To  start  the  recovery  suite,  start  the  backup  installer  and  select  option  10.    

The  installer  will  ask  you  if  you  want  to  continue  and  download  the  restorescript   (will  be  automatically  started  after  download),  select  “Yes”  to  continue.  

 

The  script  will  start  with  a  greeter  and  after  selecting  “OK”  will  return  the   following  menu:  

 

   

Note:  

Depending  on  the  configuration  options  the  menu  can  show  different  options.  If   you  have  MySQL  dumps  disabled,  this  option  will  not  be  visible.    

 

We  will  explain  the  steps  you  need  to  undertake  in  recovering  your  data,  this  will   not  be  a  thorough  explanation,  because  the  dialogs  presented  are  clear  and   understandable.  

 

Recovering  files  or  folders:  

1. Select  option  1  on  the  main  menu.  

(19)

4. Enter  the  absolute  (full  path)  to  the  file  or  folder  you  wish  to  restore  on   your  machine  and  agree  to  the  restoration  process.  

The  actual  restore  process  may  take  a  long  while  depending  on  the  amount   of  files  in  the  folder  or  the  size  of  the  file  you  wish  to  restore,  don’t  interrupt   the  script  during  this  step!  

5. When  the  restoration  process  is  finished,  you’ll  be  shown  a  window  with   the  files  and/or  folders  that  were  restored.  

 

Recovering  MySQL  databases:  

1. Select  option  2  on  the  main  menu.  

2. Select  the  pool  you  want  to  recover  from  a.  

3. Select  the  day  (in  case  of  the  daily  pool)  or  enter  the  month/week  number   (in  case  of  week  of  monthly  pool)  a.  

4. Enter  the  source  (original)  database.   5. Enter  the  target  (destination)  database  b.  

If  the  source  and  target  database  are  the  same,  the  script  will  warn  you  that   this  will  delete  the  original  database  on  the  machine  and  restore  it  from  the   backup,  see  note  b  for  more  details.  

6. Check  your  entered  details  in  the  confirmation  window  and  select  “Yes”  to   start  the  restoration  process.  

The  actual  restore  process  may  take  a  long  while  depending  on  the  size  of   the  database  you  wish  to  restore,  don’t  interrupt  the  script  during  this  step!   7. When  the  restoration  process  is  finished,  you’ll  be  shown  a  window  

confirming  a  successful  restore.    

Note  A:  

The  pools  available  to  you  are  pulled  from  the  backup  configuration  file.  If  you   don’t  have  any  extra  weekly  and/or  monthly  retention  set  up,  these  pools  will   not  be  available  to  you.  Also  note  that  you  can  only  recover  data  from  the  pools   that  are  already  filled  with  data.  If,  for  example,  you  have  installed  the  script  one   week  ago  and  set  up  5  extra  weeks  of  retention,  you  can  only  use  the  first  weekly   retention  pool,  because  the  other  weeks  have  not  passed  yet.  This  also  applies  to   the  monthly  backup.  

 

Note  B:  

The  source  and  target  database  may  be  the  same,  but  may  be  only  used  to   recover  the  source  database  on  the  machine,  the  local  database  will  be  dropped   and  the  database  pulled  from  the  backup  will  be  put  into  place  with  that  same   name.  Should  you  wish  to  recover  the  database  aside  of  the  original  one,  please   use  a  different  name.  

(20)

Help  functionality  

 

The  installer  has  a  built-­‐in  help  function,  which  can  provide  information   regarding  your  backups,  installation  and  support.

Glossary  

 

Below  is  a  list  of  common  used  terms  and  their  explanation.    

Retention  

Retention  is  simply  defined  as  how  long  the  backupserver  will  keep  your  data.  In   the  backupscript  you  have  at  least  a  minimum  of  1  whole  week  and  with  options   to  enable  extra  weekly  and  monthly  retention  for  a  maximum  of  52  weeks   and/or  12  months.  

 

Incremental  /  Differential  backup  

The  incremental  style  repository  aims  to  make  it  more  feasible  to  store  backups   from  more  points  in  time  by  organizing  the  data  into  increments  of  change   between  points  in  time.  This  eliminates  the  need  to  store  duplicate  copies  of   unchanged  data.  This  starts  out  with  a  full  backup  (of  all  files)  and  after  that,  any   number  of  incremental  or  differential  backups  are  made  for  the  current  week   and/or  extra  retention  that  is  given.  

 

SSH  (public)  key  

SSH  keys  serve  as  a  means  of  identifying  yourself  to  an  SSH  server  using  public-­‐ key  cryptography  and  challenge-­‐response  authentication.  One  immediate  

advantange  this  method  has  over  traditional  password  authentication  is  that  you   can  be  authenticated  by  the  server  without  ever  having  to  send  your  password   over  the  network.  Anyone  eavesdropping  on  your  connection  will  not  be  able  to   intercept  and  crack  your  password  because  it  is  never  actually  transmitted.   Additionally,  Using  SSH  keys  for  authentication  virtually  eliminates  the  risk   posed  by  brute-­‐force  password  attacks  by  drastically  reducing  the  chances  of  the   attacker  correctly  guessing  the  proper  credentials.  

 

Crontab  /  cronjob  

Cron  is  a  powerful  job  scheduler  for  GNU/Linux  and  many  other  operating   systems.  It  automates  recurring  tasks  by  executing  commands  at  a  given  time.  It   has  a  wide  range  of  potential  applications;  most  simple  recurring  tasks,  from
