snaps —
easy and
secure remote snapshots
| snaps |
[-fhnqvV]
[-c
configfile]
[-s
filter] |
The
snaps utility takes snapshots of remote
locations using
ssh(1) and
hrsync(1), which is a hardened version of rsync.
Each location is being isolated from other locations that are being backed up
in order to mitigate against a compromised remote host.
The following arguments are supported:
-
-
- -f
- Force taking a new snapshot, even if the last snapshot has
not yet expired.
-
-
- -h
- Print the synopsis of
snaps.
-
-
- -n
- Only check the syntax of the config file and exit.
-
-
- -q
- Be quiet, except for errors.
-
-
- -v
- Be more verbose. Multiple occurrences increase the
verbosity level.
-
-
- -V
- Print the current version of
snaps and exit.
-
-
- -c
configfile
- Use an alternate configuration file. The default config
file used is /etc/snaps.conf.
-
-
- -s
filter
- Only backup locations in the config file that match
filter. Each configured location is
canonicalized to user@host:path and can be filtered on any substring. This
option can be passed multiple times so that more locations are
matched.
snaps runs as an unprivileged user. This user must
have access to a public/private key pair that is used by
ssh(1) to login to each remote location.
- /etc/snaps.conf
- Default configuration file.
The
snaps utility exits 0 on success,
and >0 if an error occurs.
