Hi, I am looking at the poorman way to backup VMware guest machines. I have a script that can do a snapshot, then move that snapshot to some disk where Amanda can save it (then remove the snapshot).
It's ugly because it does not support any kind of granularity and only allows full abck-up. But it is still better than nothing. Doing the snapshot will be run through Amanda pre and post scripts. But I am wondering how to do for the size estimate: my script can return the estimate size (the size of the allocated virtual disk). Usually the size if computed by a gnutar --total... but I don't need to run it, I have no data to give it to read, in fact the snapshot will only be generated at the dump time, if and only if the planner decides there should be a dump. How to arrange my configuration for a pre-script to return the estimated size and gtar --total be avoided? Best regards, Olivier --
