Managing the AMASS File System
Backup Example for Large File Systems
The following script backs up data on large file systems. Consequently, a full backup completes over an extended period of time, usually one month.
Step 1. On the first day of the month (day 1) the script generates two lists:
•A complete list of files
•A list of files that have changed since the last complete backup
Step 2. The shell variable NMEGS determines how much data the system can back up in one evening.
Note
The amount of data can exceed the capacity of one optical platter.
Step 3. Every day, the script does a partial backup within a manageable period of time (one evening) of a group of volumes in a volume group.
Therefore, if you can divide the AMASS file system into 20 parts, the script can do a complete backup in 20 days.
