3. Specify what to backup by selecting source folders.
4. Add backup schedules by clicking the Add a Schedule hyperlink.
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.
Next, choose the destination: the original location or alternative location. If the original location is
selected, it will restore the files to exactly where they are backed up. If the original volume is missing,
it will not restore anything. If the original folders are missing, it will create the folders automatically.
If the alternative location is selected, it will restore data to a user-specified location. The full tree
hierarchy of backup data will be reconstructed under that location.
Restore security: when checked, it will restore the access control lists (ACL) together with the data.
Overwrite Options – specify whether to overwrite the existing files with the backed up files.
