Guys.
I have about twenty boxes I need to back up. I been told that cpio is go to do that, I currently use tar but by directory by directory casee, but I am having problems finding a good example of a back up script. I am looking to make a cpio image of the whole box. Lucky we have a SAN with storage that will be able to hold the back up.
I don't think there's any reason to prefer cpio over tar. It's a less-used and more antiquated format. TAR also permits more compressions schemes (in fact, beyond the ones it will invoke itself based on options like 'j' or 'z', it can run arbitrary external compression commands if you wish). I recommend you stick with your tar-based scheme, if its suits you. Depending on your needs, an rsync approach might be a better choice. One thing I've taken to doing is augmenting my automated backup based on CrashPlan with a rotating (currently just every other day) rsync snapshots of critical directories. It's a lot easier to recover a lost or clobbered file from one of these than it is to poke around in the GUI for CrashPlan, but CrashPlan keeps history, is secure, compresses its backup archives, handles multiple backup destinations (including drives and remote systems), etc., so is still good to have as baseline backup mechanism.
