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. 
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.
Note
The amount of data can exceed the capacity of one 
optical platter.
