Using a Tape Library
a) Select the tape drive. Usually it is set to Auto , allowing
the NAS server to choose any available tape drive to
do the backups.
b) Select backup media. Please define a media pool on
the Backup Tape Library Media Pool menu if there is
no media pool.
c) Choose to make full backups or incremental backup.
A full backup will copy all selected data. An
incremental backup will only copy those data with
archive bits set.
d) Set schedules.
e) Specify the tape retention period. A retention period is
the number of days in which you want to keep the
backup data from being overwritten. For example, if
the retention period is set to 7 days, the tape will
remain in the save set as long as it has been used and
be moved to the scratch set when it has not been
used for 7 days.
f) Set overwrite options. If Overwrite the media is
selected, it will only use blank tape or scratch tape for
backups and write data from the beginning of the
tapes. If
Append to the media is selected, it will
append data to the last used tape.
5. Specify whether to enable the hardware compression
capability of the tape drives.
6. Click Apply to start to back up.
Restoring Data
To restore data, go to the Backup Tape Library Restore
menu. First, select the backup task which created the backup
sets. Then select a backup set and specify whether to restore
all files or only partial of them. To view the information of the
backup set, click the hyperlink in the
Backup Type column.
Next, choose to restore all files or only certain files or folders. For
the latter, you need to install Sun Java virtual machine v1.4 or
higher. Please go to http://java.sun.com and download the
software. Use the Java UI to select the files or folders to be
restored.
