rsnapshot |
linuxserver/rsnapshot
Rsnapshot is a filesystem snapshot utility based on rsync. rsnapshot makes it easy to make periodic snapshots of local machines, and remote machines over ssh. The code makes extensive use of hard links whenever possible, to greatly reduce the disk space required."
Supported Architectures
We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling lscr.io/linuxserver/rsnapshot:latest
should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
The architectures supported by this image are:
Architecture | Available | Tag |
---|---|---|
x86-64 | ✅ | amd64-<version tag> |
arm64 | ✅ | arm64v8-<version tag> |
armhf | ❌ |
Application Setup
IMPORTANT NOTES:
After starting the container you will need to edit /config/rsnapshot.conf
.
SNAPSHOT ROOT DIRECTORY
rsnapshot is configured to backup data to the /.snapshots
volume by default.
This can be changed in the config, but be sure you mount a volume to the container to match.
BACKUP LEVELS / INTERVALS
rsnapshot retains backups based on configurations in this section. Please see the rsnapshot readme for more information.
BACKUP POINTS
rsnapshot is configured to backup data from the /data
volume by default.
This can be changed in the config, but be sure you mount a volume to the container to match.
cron
You will then need to edit /config/crontabs/root
to set cron jobs to run rsnapshot.
By default no cron jobs are enabled. Examples are includes based on information from the rsnapshot readme.
Usage
To help you get started creating a container from this image you can either use docker-compose or the docker cli.

Parameters
Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal>
respectively. For example, -p 8080:80
would expose port 80
from inside the container to be accessible from the host's IP on port 8080
outside the container.
Ports (-p
)
Parameter | Function |

Environment Variables (-e
)
Env | Function |
---|---|
PUID=1000 |
for UserID - see below for explanation |
PGID=1000 |
for GroupID - see below for explanation |
TZ=Etc/UTC |
specify a timezone to use, see this list. |
Volume Mappings (-v
)
Volume | Function |
---|---|
/config |
Contains all relevant configuration files. |
/.snapshots |
Storage location for all snapshots. |
/data |
Storage location for data to be backed up. |
Miscellaneous Options
Parameter | Function |
---|
Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend FILE__
.
As an example:
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Will set the environment variable PASSWORD
based on the contents of the /run/secrets/mysecretpassword
file.
Umask for running applications
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022
setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.
User / Group Identifiers
When using volumes (-v
flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID
and group PGID
.
Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.
In this instance PUID=1000
and PGID=1000
, to find yours use id user
as below:
$ id username
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
Docker Mods
We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
Support Info
- Shell access whilst the container is running:
docker exec -it rsnapshot /bin/bash
- To monitor the logs of the container in realtime:
docker logs -f rsnapshot
- Container version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' rsnapshot
- Image version number
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/rsnapshot:latest
