Protecting Local Disks - 118
If you select Base Disk, a backup of that disk image on the storage system is created, and this backup
is recovered. As a result, if the maximum number of backups have already been performed, the oldest
backup is deleted to make room for this backup.
12. Specify whether or not to delete all backups that occurred after the selected date by selecting or clear-
ing Rollback the remote disk.
13. Specify whether or not to scan the differences between the backup and the disk to which you are
recovering data by selecting or clearing
Enable micro-scan.
If you are simply overwriting corrupted data on the same disk that you protected previously, select this
option. DiskSafe Express will scan both the backup and the disk, and copy only the data that differs
between the two. This can minimize the impact to the network, although the scanning process takes
some additional time.
If you are recovering the backup to a brand new disk, clear this option. DiskSafe Express will copy all
the data from the backup to the new disk without doing any scanning (there will be nothing to scan on
the new disk).
14. Select Next.
15. Select the disk where you want to recover the data, and select Next.
16. If you selected the backup of a disk in step 10, go to step 18.
If you selected the backup of a partition in step 10, select Restore to a partition to recover to an exist-
ing partition on the selected disk, or select Clear all partitions and create new to delete all the exist-
ing data on the selected disk and recover only the selected partition.
17. If you selected Restore to a partition in step 16, select the partition where you want to recover the
data, and then select Next. (Otherwise, go to step 18.)
18. Select Yes to confirm the action.
The status screen displays the progress of the recovery. You can cancel it at any time by selecting
Abort. However, this leaves the disk or partition in an incomplete state (some of the data will have
been recovered, but not all of it).
Caution: This action is not reversible. If you select this option, you will not be able to subsequently
recover from another later backup.
Note: If you are recovering a system disk, the system to which you are recovering the data must be
identical to the original system. For example, if the original system had a particular type of
network adapter, the system to which you are recovering the data must have the exact same
type of network adapter. Otherwise, the recovered files will not operate properly.
Caution: This overwrites any existing data on the selected disk. Although you can subsequently
recover different data, you cannot recover the original data.
