SuperDuper - Backup made super simple
Authored by: SOX on Mar 15, '06 08:32:10AM
Currently I have two favorite backup schema 1) rdiff-backup for remote backups. It's very stable and recovers gracefully when a transmission error borks the backup. It makes differential snapshots too so you can revert to any previous backup. These are backward not forward diffs so the most recent backup is preserved as a mirror copy on the disk easily accessed directly from the OS. It works across different Operating systems. For HFS to HFS backup you need to know two obscure command flags

--override-chars-to-quote '' and --nocarbonfile

Drawbacks are that you need it installed on both machines to work and the versions number must match. It has nice stats reporting and does not fail silently. As fast as rsync but much more reliable and has differential backups. It's in Fink

2) for local or mounted disk backups I use silver keep (or maybe super duper) to the initial copy. Then in the directory holding the backup file system I execute
find -d myBackup | cpio -dpl myBackup`date "+%y%m%d_%H:%M"`
this creates a "zero space" snapshot of the files.
