And if you are doing daily backups of a lot of stuff then you can run out of inodes. In fact, even for BackupPC, people have run out of inodes. Also, I imagine it is slower since rsync just looks for changed files while 'cp -al' needs to create all those hard links. On the other hand, if you are just backing up home directories on two computers, BackupPC may be overkill. ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
