Managing the AMASS File System

amassbackup

Back up to a Backup Volume in either a library or a standalone drive the following files:

File System Database (/usr/filesysdb)

Journal (/usr/filesysdb/journal)

Note

When an external tape device is used to backup the AMASS database (with -d flag) amassbackup will always unload the tape from the drive after successful backup completion.

While the backup is being completed, the Database is locked.

Therefore, client requests cannot be satisfied.
