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') ~/

--rm
--volumes-from backup

--env AWS_SECRET_ACCESS_KEY=aokjsvdn0e2nc08va80428b308jcwa08je02983jr032
amdavidson/backup-server
restic -r s3:s3.wasabisys.com/other-container init

--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
