Validating Vaults, Archives And Backups - ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual

chroot /mnt/system/ /usr/sbin/grub
9. Specify the disk on which GRUB is located—typically, the boot or root partition:
root (hd0,0)
10. Install GRUB. For example, to install GRUB in the master boot record (MBR) of the first disk, run
the following command:
setup (hd0)
11. Exit the GRUB shell:
quit
12. Unmount the mounted file systems and then reboot:
umount /mnt/system/dev/
umount /mnt/system/proc/
umount /mnt/system/boot/
umount /mnt/system/
reboot
13. Reconfigure the bootloader by using tools and documentation from the Linux distribution that
you use. For example, in Debian and Ubuntu, you may need to edit some commented lines in the
/boot/grub/menu.lst file and then run the update-grub script; otherwise, the changes might not
take effect.

6.4 Validating vaults, archives and backups

Validation is an operation that checks the possibility of data recovery from a backup.
Validation of a file backup imitates recovery of all files from the backup to a dummy destination.
Validation of a disk or volume backup calculates a checksum for every data block saved in the
backup. Both procedures are resource-intensive.
Validation of an archive will validate all the archive's backups. A vault (or a location) validation will
validate all archives stored in this vault (location).
While successful validation means high probability of successful recovery, it does not check all factors
that influence the recovery process. If you back up the operating system, only a test recovery in
bootable environment to a spare hard drive can guarantee success of the recovery. At least ensure
that the backup can be successfully validated using the bootable media.
Different ways to create a validation task
Using the Validation page is the most general way to create a validation task. Here you can validate
immediately or set up a validation schedule for any backup, archive or location you have permission
to access.
Validation of an archive or of the latest backup in the archive can be scheduled as part of the backup
plan. For more information see the Creating a backup plan (p. 102) section.
You can access the Validation page from the Vaults (p. 70) view. Right-click the object to validate
(archive, backup or vault) and select Validate from the context menu. The Validation page will be
opened with the pre-selected object as a source. All you need to do is to select when to validate and
(optionally) provide a name for the task.
