7 bup-save - create a new bup backup set
11 bup save [-r *host*:*path*] \<-t|-c|-n *name*\> [-#] [-f *indexfile*]
12 [-v] [-q] [\--smaller=*maxsize*] \<paths...\>;
16 `bup save` saves the contents of the given files or paths
17 into a new backup set and optionally names that backup set.
19 Before trying to save files using `bup save`, you should
20 first update the index using `bup index`. The reasons
21 for separating the two steps are described in the man page
24 By default, metadata will be saved for every path, and the metadata
25 for any unindexed parent directories of indexed paths will be taken
26 directly from the filesystem. However, if `--strip`, `--strip-path`,
27 or `--graft` is specified, metadata will not be saved for the root
28 directory (*/*). See `bup-restore`(1) for more information about the
33 -r, \--remote=*host*:*path*
34 : save the backup set to the given remote server. If
35 *path* is omitted, uses the default path on the remote
36 server (you still need to include the ':'). The connection to the
37 remote server is made with SSH. If you'd like to specify which port, user
38 or private key to use for the SSH connection, we recommend you use the
42 : after creating the backup set, print out the git tree
43 id of the resulting backup.
46 : after creating the backup set, print out the git commit
47 id of the resulting backup.
50 : after creating the backup set, create a git branch
51 named *name* so that the backup can be accessed using
52 that name. If *name* already exists, the new backup
53 will be considered a descendant of the old *name*.
54 (Thus, you can continually create new backup sets with
55 the same name, and later view the history of that
56 backup set to see how files have changed over time.)
59 : specify the date of the backup, in seconds since the epoch, instead
62 -f, \--indexfile=*indexfile*
63 : use a different index filename instead of
67 : increase verbosity (can be used more than once). With
68 one -v, prints every directory name as it gets backed up. With
69 two -v, also prints every filename.
72 : disable progress messages.
75 : don't back up files >= *maxsize* bytes. You can use
76 this to run frequent incremental backups of your small
77 files, which can usually be backed up quickly, and skip
78 over large ones (like virtual machine images) which
79 take longer. Then you can back up the large files
80 less frequently. Use a suffix like k, M, or G to
81 specify multiples of 1024, 1024*1024, 1024*1024*1024
84 \--bwlimit=*bytes/sec*
85 : don't transmit more than *bytes/sec* bytes per second
86 to the server. This is good for making your backups
87 not suck up all your network bandwidth. Use a suffix
88 like k, M, or G to specify multiples of 1024,
89 1024*1024, 1024*1024*1024 respectively.
92 : strips the path that is given from all files and directories.
94 A directory */root/chroot/etc* saved with "bup save -n chroot
95 \--strip /root/chroot" would be saved as */etc*. Note that
96 currently, metadata will not be saved for the root directory (*/*)
97 when this option is specified.
99 \--strip-path=*path-prefix*
100 : strips the given path prefix *path-prefix* from all
101 files and directories.
103 A directory */root/chroot/webserver* saved with "bup save -n
104 webserver \--strip-path=/root/chroot" would be saved as
105 */webserver/etc*. Note that currently, metadata will not be saved
106 for the root directory (*/*) when this option is specified.
108 \--graft=*old_path*=*new_path*
109 : a graft point *old_path*=*new_path* (can be used more than
112 A directory */root/chroot/a/etc* saved with "bup save -n chroot
113 \--graft /root/chroot/a=/chroot/a" would be saved as
114 */chroot/a/etc*. Note that currently, metadata will not be saved
115 for the root directory (*/*) when this option is specified.
117 -*#*, \--compress=*#*
118 : set the compression level to # (a value from 0-9, where
119 9 is the highest and 0 is no compression). The default
120 is 1 (fast, loose compression)
