Backup levels are confusing me. Here's what I want - Full backup on Fri,

- any file that has changed since the last FULL backup.
On my schedule, the full is easy enough. But the description of
"incremental" - "Backs up files that have changed since the last backup,
regardless of level. " sounds a lot like differential. Or is differential
a level 1 - "A level 1 backup backs up all files that have changed since
the most recent full backup (considered a level zero).". This sounds
exactly like a differential to me. :-)
So do a do a FULL on Fri, and a level 1 on Mon - Thu? Or is it
incremental?
A differential is any numbered level in NetWorker. If you just want
plain old differentials, pick a number (say 5, or 1) and stick with it.
An incremental is NOT a differential. An incremental backs up anything
that changed since the last backup of any level, and as such may require
many backups in order to restore a full filesystem.
NetWorker gives you multiple numbered levels for extra functionality. If
you don't want this extra functionality, just use level 5 each day and
call it a differential.
