The "Add XenServer Settings" page is used to configure Vembu OnlineBackup with
XenServer. Vembu OnlineBackup will use the credentials to connect to the XenServer while listing the database(s) or while taking XenServer backup.
Select XenServer for backup:
This choice-box will list all the XenServers added in the client installation. You should choose the XenServer which Vembu OnlineBackup should connect to. Vembu
OnlineBackup will connect to this XenServer and list the Guest OSes registered in this XenServer to enable you to configure backup schedules for the virtual machines. Next Button:
Select the XenServer and click Next button, it will take you to the XenServer Backup Configuration page.

Configure XenServer Backup
Step 1: Schedule Name
The first step in configuring a backup is to give a name for the backup schedule. The backup schedule name will uniquely identify the backup. While restoring your backup data, you need to choose the data to be restored using its schedule name.
Step 2: Select Guest OS(s)
On the left side of the "Add XenServer Backup" Page, is the tree with a list of Guest OSes available in the XenServer. Select Guest OS that need to be backed up as part of this schedule.
Step 3: Set Basic Configuration
Backup Type
Vembu OnlineBackup provides 2 types of Backup options.
1. Seed Backup – With this option you can seed backup to local drive which you can migrate to the Vembu Cloud using USB/External Hard drives to avoid more network bandwidth. It can be done only with the initial Full backup and incremental backup will not be continued.
2. Vembu Cloud – With this option you can directly backup the data into the Vembu Cloud over the Internet.
Test connectivity - Before you proceed with the backup, you can check the connectivity to Backup Server (Vembu Cloud). It will check the Connectivity and DNS Lookup with the Vembu Cloud.

Step 4: Scheduling (Decide When To Backup)
With XenServer Backup we can perform 3 types of scheduling options as per the requirements.
Run Daily
Choose the time at which the backup should run daily. This will execute the backup everyday at the time you have provided. Unless you’ve selected the “Run this Backup each time Vembu restarts” option in Advanced Options, Vembu will run at the stipulated time only.
Run Weekly
Choose the time and the day of the week the backup should run. Vembu will execute the backup every week on the particular day and time chosen. Note that you can select multiple days of the week if you wish to run the backup on multiple days of the week. Unless you’ve selected the “Run this Backup each time Vembu restarts” option in Advanced Options, Vembu will run at the stipulated time/day only.
Run Monthly
Choose the time and day of the month the backup should run. Vembu will run the backup every month on the particular day and time chosen. Vembu will run at the stipulated time/day only.
Step 5: Additional Full Backup
Typically, you would do a full backup first time you backup your data and thereafter only do incremental backups. However, like in a typical enterprise scenario, if you want to run full backups periodically and run the incremental backups in between two full backups you can Configure Additional Full Backup (Additional full backup schedule is mandatory to keep the incremental limited. Please configure an additional full backup for this schedule).
Vembu OnlineBackup | Admin User Guide | XenServer Backup and Restore 107 For 'Run Every Few Hours/Run Daily' incremental backups, the Additional Full Backup settings will allow you to configure daily/weekly/monthly additional full backups. For weekly and monthly backups, only Monthly additional full backups are possible.
Additionally you can specify the maximum number of full backups that need to be stored in the server. For example if you configured a weekly backup and additionally if you configure a monthly full backup, then Vembu OnlineBackup will take a full backup first time and then weekly do an incremental backup. The next month, Vembu OnlineBackup will do a new full backup and subsequently run the weekly incremental backup over this full backup. After 6 months you will have 6 separate full backups in the Vembu Cloud along with weekly
incremental versions under each of the 6 full backups. If you have configured to store only 6 full backups "Store maximum of 6 full backups" here. On the 7th month, Vembu OnlineBackup, after finishing the 7th full backup, will delete the first full backup along with its weekly incremental backups thus retaining always the last 6 month backups.
Note:
The Default full-backup to store is 2Advanced Options
If you want to configure some additional advanced options - like, restarting the failed backup etc. click on the Advanced Options button.
Advanced Backup Schedule Settings
There are three options here on how the backup should be scheduled.
1. Runthis backup each time Vembu OnlineBackup restarts – If you enable this option by checking the check box, then this backup schedule will be run every time Vembu
OnlineBackup is restarted or the machine is rebooted irrespective of the actual schedule time of this backup schedule. This is to ensure that any modified or new files created when Vembu OnlineBackup was down are backed up as soon as possible. In case of the Continuous backup or ‘Run every…’ scheduling options, backups will run each time Vembu OnlineBackup restarts – by default.
2. Run this backup immediately after saving this configuration (thereafter, Backups will be scheduled as per the schedule stipulated) - If you enable this option, then this backup schedule will be executed once immediately after you save this backup schedule – even if it's not yet ‘time’ as per the schedule. For example if you configure a daily backup at 10.00 AM but you configured the backup at 8.00 AM, then the backup
schedule will be run once immediately (8.00 AM) and then as per schedule (e.g. daily at 10.00 AM).
3. Attempt to run this backup every 5 minutes in case of non-completion because of a problem (Network error etc.) - If enabled, the user can choose to reschedule this backup every 5/10/15/20/25/30 minutes, whenever an attempted backup is incomplete
Vembu OnlineBackup | Admin User Guide | XenServer Backup and Restore 108 because of a network error, server crash etc. The number of times the backup will be rescheduled (due to an error) can be configured to be in between 1-5 or unlimited, with the default setting as 5. This is to ensure that an incomplete backup is completed as soon as possible without waiting for the next actual schedule time. Note that this option is enabled by default.
Saving the configured backup
Once all the Guest OSes to be backed up are chosen and the configuration options are set, you simply need to click on the "Configure/Save Backup” button to activate the backup as per the schedule- on to the Vembu Cloud.
