If the system would happen to crash (or suffer a power outage, or whatever) during the creation of an image, simply chuck out that image. If the problem occurs while there's no writes happening, then there's no downside. Not logging the data but only the metadata hurts in live systems, it's much less of a problem in a backup system. What is also helpful is that xfs is *very* fast in deleting files. On a 8TB backup system, expiring the images for one day used to take around 24 hours (with reiserfs, although in my experience ext3 is not that much faster in deleting). That meant that sometimes the expire of one day took longer than one day... Now with xfs it's a couple of hours. For production systems I use ext3 nowadays, whereas I used to use reiserfs. When created with -O dir_index,filetype most of the perceived problems with ext3 in the past are gone. For lots of small files though ext3 isn't so space-efficient (as [EMAIL PROTECTED] discovered).
