After 30+ hardlinks to each file built up, filesystem operations slowed down - not in a killer way, but I did notice it. I think it's better to just use --backup and write the previous version to a new dir with --backup-dir=`date +%F` or some such scheme. You don't see the backups represented as a whole directory structure, but it's less messy. -- Toby Bluhm Alltech Medical Systems America, Inc. 30825 Aurora Road Suite 100 Solon Ohio 44139 440-424-2240
