backup rotations - advice required
We currently run a backup rotation of 1 monthly full backup, monday to thursday incremental and friday differential via archive bit. Does this work as a strategy?
One of the problems we have is the daily incremental for certain folder doesnt seem to be backing up files that are changed on that day but everything in that particular folder. Is this because we are using archive bit instead of modified time seeming as everything in said folder is replaced daily but since its being copied and replaced by a batch file daily the modified time doesnt change?
That wouldnt explain however why the weekly differential backup which is usually smaller than the daily incrementals?
Any advice welcome.
