They don't use much space, because "cp -al" uses hard links to do the copies. Therefore, a file that's in all backup sets takes up only the space necessary to store it once. This ties nicely with how rsync does a delete. When a file gets deleted from the new backup set (or replaced with an updated copy), the old versions are not affected. This guy explains it a lot better. It's where I got the script from. http://www.mikerubel.org/computers/rsync_snapshots/ - -- Steve -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkonodcACgkQeERILVgMyvC69gCeKWLC+9ytaNKQxT16OESOpck5 xncAnjfBFUlE55H3uHNrBSMaXia6tOO4 =IUs1 -----END PGP SIGNATURE----- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
