Hi,
we are about to build up a backup system onto a network drive. We do
not need long term full backup, we just want to be able to access data
maximal a month old.
We thought of doing one full backup and then just doing cumulative
backups. We are planning on using it over a longer period and since
after a year the data can differ a lot from the original full backup
each cumulative backup can get quite large. A possibility of course is
to do a full backup now and then.
My question is, that instead of working with cumulative backup I want
to use incremental ones. Now normally at the end of a cycle the oldest
incremental backup is overwritten and the whole backup becomes
worthless. Is there a method were the oldest increments is included
into the full backup itself after a cycle has been reached?
Example:
- one full backup
- 10 increments
before starting increment 11. Renew full backup by including oldest
incremental backup.
Thanks in advance for any help or pointers.
You should take a look at this:
http://wiki.zmanda.com/index.php/FAQ:How_are_backup_levels_defined_and_how_does_Amanda_use_them%3F
before launching off into backup strategy ideas based on prior knowledge
from other kinds of backup software. After you have read through that a
couple of times, you might have different questions.
