Not with rsync or rsnapshot. If you make a change in one line to a 48GB file, rsnapshot will remove the appropriate hard link (leaving the others alone) and create a new 48GB file at a new inode. (Because rsnapshot uses rsync, the data transfer for this change is still fast, but it's still 2x storage.) --keith -- kkeller@xxxxxxxxxxxxxxxxxxxxxxxxxx _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
