 To back up data to a locally attached tape device, expand the Tape drives group, then click the
required device.
2. Using the archives table
To assist you with choosing the right destination, the table displays the names of the archives
contained in each location you select. While you are reviewing the location content, archives can
be added, deleted or modified by another user or by the program itself according to scheduled
operations. Use the Refresh button to refresh the list of archives.
3. Naming the new archive
Once you select the archive destination, the program generates a name for the new archive and
displays it in the Name field. The name commonly looks like Archive(1). The generated name is
unique within the selected location. If you are satisfied with the automatically generated name,
click OK. Otherwise enter another unique name and click OK.
Backing up to an existing archive
You can configure the backup plan to back up to an existing archive. To do so, select the archive in
the archives table or type the archive name in the Name field. If the archive is protected with a
password, the program will ask for it in the pop-up window.
By selecting the existing archive, you are meddling in the area of another backup plan that uses the
archive. This is not an issue if the other plan is discontinued, but in general you should follow the
rule: "one backup plan - one archive". Doing the opposite will not prevent the program from
functioning but is not practical or efficient, except for some specific cases.
Why two or more plans should not back up to the same archive
1. Backing up different sources to the same archive makes using the archive difficult from the
usability standpoint. When it comes to recovery, every second counts, but you might be lost in
the archive content.
Backup plans that operate with the same archive should back up the same data items (say, both
plans back up volume C.)
2. Applying multiple retention rules to an archive makes the archive content in some way
unpredictable. Since each of the rules will be applied to the entire archive, the backups belonging
to one backup plan can be easily deleted along with the backups belonging to the other. You
should especially not expect the classic behavior of the GFS and Tower of Hanoi backup schemes.
Normally, each complex backup plan should back up to its own archive.
6.2.8 Simplified naming of backup files
If you select the Name backup files using the archive name... check box:
 The file name of the first (full) backup in the archive will consist of the archive name; for
example: MyData.tib. The file names of subsequent (incremental or differential) backups will
have an index; for example: MyData2.tib, MyData3.tib, and so on.
This simple naming scheme enables you to create a portable image of a machine on a detachable
media or move the backups to a different location by using a script.
 Before creating a new full backup, the software will delete the entire archive and start a new
one.
This behavior is useful when you rotate USB hard drives and want each drive to keep a single full
backup (p. 126) or all backups created during a week (p. 126). But you might end up with no
backups if a full backup to your only drive fails.
