NAME
bup-save - create a new bup backup set
SYNOPSIS
bup save [-r host:path] <-t|-c|-n name> [-#] [-f indexfile] [-v] [-q] [--smaller=maxsize]
DESCRIPTION
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).
OPTIONS
-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 ':'). The connection to the remote server is made with SSH. If you'd like to specify which port, user or private key
to use for the SSH connection, we recommend you use the ~/.ssh/config file.
-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.)
-f, --indexfile=indexfile
use a different index filename instead of ~/.bup/bupindex.
-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. Use a suffix like k, M, or G to specify multiples of 1024, 10241024, 10241024*1024 respectively.
--bwlimit=bytes/sec
don't transmit more than bytes/sec bytes per second to the server. This is good for making your backups not suck up all your net-
work bandwidth. Use a suffix like k, M, or G to specify multiples of 1024, 10241024, 10241024*1024 respectively.
--strip
strips the path that is given from all files and directories.
A directory /root/chroot/etc saved with "bup save -n chroot --strip /root/chroot" would be saved as /etc.
--strip-prefix=path-prefix
strips the given path-prefix path-prefix from all files and directories.
A directory /root/chroots/webserver saved with "bup save -n webserver --strip-path=/root/chroots" would be saved as /webserver/etc
--graft=old_path=new_path
a graft point old_path=new_path (can be used more than once).
A directory /root/chroot/a/etc saved with "bup save -n chroots --graft /root/chroot/a/etc=/chroots/a" would be saved as
/chroots/a/etc
-#, --compress=#
set the compression level to # (a value from 0-9, where 9 is the highest and 0 is no compression). The default is 1 (fast, loose
compression)
EXAMPLE
$ bup index -ux /etc
Indexing: 1981, done.
$ bup save -r myserver: -n my-pc-backup --bwlimit=50k /etc
Reading index: 1981, done.
Saving: 100.00% (998/998k, 1981/1981 files), done.
$ ls /home/joe/chroots/httpd
bin var
$ bup index -ux /home/joe/chroots/httpd
Indexing: 1337, done.
$ bup save --strip -n joes-httpd-chroot /home/joe/chroots/httpd
Reading index: 1337, done.
Saving: 100.00% (998/998k, 1337/1337 files), done.
$ bup ls joes-httpd-chroot/latest/
