Incremental Backups - Determine the overlap factor (-io)

Posted by Admin on 31-Mar-2011 03:16

Is there a way of programatically determining the overlap factor (-io) so that an incremental backup always backs up any changes since the last full backup?

i.e.

Sun: Full Backup

Mon: Incremental (-io 1)

Tue: Incremental (-io 2)

Web: Incremental (-io 3)

I'm hoping to avoid hard-coding the overlap figure.

Thanks, Chris

I suggest you do a full backup to disk every day and then roll that backup image off to your preferred media.  My expeience is that the time difference between a full backup and an incrmental one is not worth the trouble and the full backup gives you a faster and easier restore point.

And, of course, implement AI if you haven't already.
