bup-save - create a new bup backup set
bup save [-r host:path] <-t|-c|-n name> [-v] [-q] [--smaller=maxsize] <paths...>
bup save saves the contents of the given files or paths
into a new backup set and optionally names that backup set.
Before trying to save files using bup save, you should
first update the index using bup index. The reasons
for separating the two steps are described in the man page
for bup-index(1).
-r, --remote=host:path : save the backup set to the given remote server. If path is omitted, uses the default path on the remote server (you still need to include the ':')
-t, --tree : after creating the backup set, print out the git tree id of the resulting backup.
-c, --commit : after creating the backup set, print out the git commit id of the resulting backup.
-n, --name=name : after creating the backup set, create a git branch named name so that the backup can be accessed using that name. If name already exists, the new backup will be considered a descendant of the old name. (Thus, you can continually create new backup sets with the same name, and later view the history of that backup set to see how files have changed over time.)
-v, --verbose : increase verbosity (can be used more than once). With one -v, prints every directory name as it gets backed up. With two -v, also prints every filename.
-q, --quiet : disable progress messages.
--smaller=maxsize : don't back up files >= maxsize bytes. You can use this to run frequent incremental backups of your small files, which can usually be backed up quickly, and skip over large ones (like virtual machine images) which take longer. Then you can back up the large files less frequently.
