Which is 'best' or 'faster'? Take a snapshot of an existing backup and then "rsync --delete" into that to make a backup of some other filesystem? Or use "rsync --link" to link a new backup tree against a previous backup tree for the some other filesystem? Which case does btrfs handle the better? Would there be any problems for doing this over an nfs mount of the btrfs? Both cases can take advantage of the raid and dedup and compression features of btrfs. Would taking a btrfs snapshot be better than rsync creating the hard links to unchanged files? Any other considerations? (There are perhaps about 5% new or changed files each time.)
