 # backup-server
-Docker based backup server
+Docker based ssh backup host with `borg` and `restic` installed. Can be effectively used for as a backup repository and a tool to backup containers.
+
+## Run a backup host and backup a client with `borg`
+
+Run the backup host with this command:
+    docker run -d \
+        --restart always \
+        --port 22:22 \
+        --volume /mnt/backup:/bkup \
+        --name backup \
+        amdavidson/backup:latest
+
+Add your ssh key to the host:
+    docker cp id_rsa.pub backup:/bkup/.ssh/authorized_keys
+    docker run --volumes-from backup amdavidson/backup-server chown 1111:1111 /bkup/.ssh/authorized_keys
+
+
+Create a repository for backups:
+    borg init backup:/bkup/client-name
+
+Periodically run a backup with a command similar to this:
+    borg create --stats --verbose backup:/bkup/client-name::$(date '+%s') ~/
+
+## Backup a container with `restic`
+
+Create a repository for backups:
+    docker run \
+        --rm \
+        --volumes-from backup \
+        --env RESTIC_PASSWORD=secretpw \
+        --env AWS_ACCESS_KEY_ID=asvc0832n20vasfdh0 \
+        --env AWS_SECRET_ACCESS_KEY=aokjsvdn0e2nc08va80428b308jcwa08je02983jr032 \
+        amdavidson/backup-server \
+        restic -r s3:s3.wasabisys.com/other-container init
+
+Perodically run a backup with a command similar to this:
+    docker run \
+        --rm \
+        --volumes-from backup \
+        --volumes-from other-container:ro \
+        --env RESTIC_PASSWORD=secretpw \
+        --env AWS_ACCESS_KEY_ID=asvc0832n20vasfdh0 \
+        --env AWS_SECRET_ACCESS_KEY=aokjsvdn0e2nc08va80428b308jcwa08je02983jr032 \
+        amdavidson/backup-server \
+        restic -r s3:s3.wasabisys.com/other-container backup /data
