Ext2/Ext3, no. They run out of inodes too fast, and it is hard to
predict where to set the inodes/bytes ratio. They also use up too
much space for directory entries - and you will be making a LOT of
I am using ReiserFS 3, though there may be better candidates. I have
had one ReiserFS disk go gunnysack on me, unrecoverable. It took a
hardware-level format to get the disk back, the Reiser tools could
not recover the data. A good reason to rotate backups.
