Essentially, they are like "pit stops" - takes a pointer behind the scenes
of NBU.
 
For those unsure of what it does (even though most do!), If checkpoint is
enabled and it hits the "pitstop" at 450GB, a marker is set. If the backup
fails at 475GB, the restart happens at 450GB, rather than ALL THE way back
to the beginning of the backup job!
 
Thats what I understand about them, and I do use them for large TB backups.

Subject: [Veritas-bu] Checkpoint on backups.



Hi,
 
Can anyone give a brief explanation of exactly what goes on when
checkpoint's are implemented on normal backup schedules. Understand what
they do but need to know what is going on in the background.
 
Cheers
 
Dave
