    How long do you keep taking diff. images as add-ons to the same original full image before you take a fresh full image and start over?

    AaLF,

    No set number. I take about 50 diffs before the increasing file size of the diff encourages me to start again with a base image. If the diff file size remained small I'd take hundreds, as unlike incrementals you aren't depending on multiple files in a chain.

    Interesting. I recently started doing differentials, but only a weeks worth. I usually image once a week (full).

    Incrementals scare me. I used to live in fear one would fail and the chain would collapse. Never happened. But the thought encouraged me to switch to diffs (and regular full images).

    I've seen it happen...not with images but with file-based tape backup. Ugly.

    I run Shadowprotect's Continuous Incrementals. I restart then periodically, but have had them running on on both machines since August.

    I recently needed some stuff from mid October and had no trouble retrieving it.

    Here is a good method of backup archiving:

    Daily Backup that keeps 7 versions (Initial full, followed by incremental)
    Weekly Backup that keeps 4 versions (Full)
    Monthly Backup that keeps up to 12 versions (Full)

    More info
