2.8 Backup
2.8.3 Selecting a destination
Click Where to back up, and then select one of the following:
Cloud storageBackups will be stored in the cloud data center.
Local foldersIf a single machine is selected, browse to a folder on the selected machine or type the folder path.
If multiple machines are selected, type the folder path. Backups will be stored in this folder on each of the selected physical machines or on the machine where the agent for virtual machines is installed. If the folder does not exist, it will be created.
Network folderThis is a folder shared via SMB/CIFS.
Browse to the required shared folder or enter the path and click the arrow button. If prompted, specify the user name and password for the shared folder.
NFS folder (available for machines running Linux or OS X)Browse to the required NFS folder or enter the path in the following format: nfs://<host name>/<exported folder>:/<subfolder>
Then, click the arrow button.
It is not possible to back up to an NFS folder protected with a password.
Secure Zone (available if it is present on each of the selected machines)Secure Zone is a secure partition on a disk of the backed-up machine. This partition has to be created manually prior to configuring a backup. For information about how to create Secure Zone, its advantages and limitations, refer to "About Secure Zone" (p. 35).
2.8.3.1
About Secure Zone
Secure Zone is a secure partition on a disk of the backed-up machine. It can store backups of disks or files of this machine.
Should the disk experience a physical failure, the backups located in the Secure Zone may be lost. That's why Secure Zone should not be the only location where a backup is stored. In enterprise environments, Secure Zone can be thought of as an intermediate location used for backup when an ordinary location is temporarily unavailable or connected through a slow or busy channel.
Why use Secure Zone?
Secure Zone:
Enables recovery of a disk to the same disk where the disk's backup resides.
Offers a cost-effective and handy method for protecting data from software malfunction, virus attack, human error.
Eliminates the need for a separate media or network connection to back up or recover the data. This is especially useful for roaming users.
Can serve as a primary destination when using replication of backups.Limitations
Secure Zone cannot be organized on a Mac.
Secure Zone is a partition on a basic disk. It cannot be organized on a dynamic disk or created as a logical volume (managed by LVM).
Secure Zone is formatted with the FAT32 file system. Because FAT32 has a 4-GB file size limit, larger backups are split when saved to Secure Zone. This does not affect the recovery procedure and speed.
Secure Zone does not support the single-file backup format (p. 102). When you change the destination to Secure Zone in a backup plan that has the Always incremental (Single-file) backup scheme, the scheme is changed to Weekly full, daily incremental.How to create Secure Zone
1. Decide which disk you want to create Secure Zone on.
2. Start the command-line interface and type acrocmd list disks to see the disk's number. 3. Use the create asz command of the acrocmd utility. The command first uses the unallocated
space on that disk and then, if the unallocated space is insufficient, takes free space from the specified volumes. For details, refer to "How creating Secure Zone transforms the disk" below. Examples:
Creating Secure Zone on disk 1 of the local machine. Secure Zone will be created with a default size that is the average between the maximum (all the unallocated space) and minimum (about 50 MB) values.acrocmd create asz --disk=1
Creating a password-protected Secure Zone of size 100 GB on disk 2 of the local machine. If the unallocated space is not enough, the space will be taken from the second volume of that disk.acrocmd create asz --disk=2 --volume=2-2 --asz_size=100gb --password=abc12345
Creating Secure Zone of size 20 GB on disk 1 of a remote machine.acrocmd create asz --host=192.168.1.2 --credentials=john,pass1 --disk=1 --asz_size=20gb
For the detailed description of the create asz command, see the command-line reference.
How creating Secure Zone transforms the disk
Secure Zone is always created at the end of the hard disk. When calculating the final layout of the volumes, the program will first use unallocated space at the end.
If there is no or not enough unallocated space at the end of the disk, but there is unallocated space between volumes, the volumes will be moved to add more unallocated space to the end.
When all unallocated space is collected but it is still not enough, the program will take free spacefrom the volumes you select, proportionally reducing the volumes' size. Resizing of locked volumes requires a reboot.
However, there should be free space on a volume, so that the operating system and applications can operate; for example, for creating temporary files. The program will not decrease a volume where free space is or becomes less than 25 percent of the total volume size. Only when all volumes on the disk have 25 percent or less free space, will the program continue decreasing the volumes proportionally.As is apparent from the above, specifying the maximum possible Secure Zone size is not advisable. You will end up with no free space on any volume, which might cause the operating system or applications to work unstably and even fail to start.
