Restoration
Access rights, file ownership, modification date, POSIX ACLs and
linux extended attributes can be changed when restoring the files.
The overwrite policy can be specified, and the files can be restored
to a new location instead of their original location. The restored
files can be verified, at two levels of reliability, after
restoration.
Find the backup data set
It is possible that there are more than one backup data sets
containing file(s) to be restored. The backup data set from which the
correct version can be restored is selected from the list of all
backup data sets currently in storage, by choosing a narrow period of
time during which the correct version was backed up.
Click on:
Select file > Navigator
In the From:
drop list, select a backup job which was
run before the file version to be restored. If you know exactly what
backup data set you want, select it from the drop list.
In the To:
drop list, select the last backup job which
contains the version you want to restore. For instance, the very last
backup may not contain the version needed, so the backup job before
the last backup will be selected. If you know exactly what backup data
set you want, select it from the drop list.
Find the file(s)
Find the file(s) to be restored:
- with the point and click file navigator, or
- by searching on the filename.

Overwrite existing files
The policy for overwriting existing files on restoration is set in
Options
.
- Overwrite: Do not restore if file exists...
- If the file exists in the location to which you are restoring,
even if it is an older version than the file in the backup data
set, it will not be restored when this box is checked.
- Overwrite: Restore if the file has been modified...
- If the existing file is newer than the same file in the backup
data set, the file in the backup data set will overwrite it on
restoration if this box is checked.
File ownership properties
The file ownership properties of restored files is set in
Options
. Select from the drop list:
- By user name
- Choose this option and Arkeia will search the
/etc/passwd
file
for the user ID that matches the owner of the files being restored.
- By user ID
- Click on this option and Arkeia will use the original user ID of
the files being restored, regardless of the entries in
/etc/passwd
.
Verification
Verification of the files is selected in the drop list
Options: Type of action
- Restoration
- The default action, restores the selected files.
- Verification Standard
- The files are checked for readability at this verification level.
- Verification High
- Select this level of verification for the highest degree of
confidence that the files are not corrupted. Individual file
checksums are computed and compared with those of the files in the
backup. It will take longer to verify at this level than at the
Standard verification level.
Please note that if one of the verification types is selected, the files
are verified but not restored.
