About

Borg Backup is a backup program that features compression deduplication, data compression and runs nicely over SSH.

https://www.borgbackup.org/

Usage

Repos

A Borg repo is where backup data is stored.

A repo can be created by running the following in an empty directory.

borg init -e none repoLocation

"-e none" is a required flag to tell bog that we don't want any encryption.

Creating a backup

When creating a backup we need to specify what kind of compression we want to use, where the repo we want to backup to is, and where the source files we want to backup are located.

borg create -C auto,lzma --progress repo/location/::name-of-backup location/to/be/backed/up

LZMA compression uses more CPU and less storage space.

Name of backup must be unique so using the date command instead of a static name is desirable when automating backups.

... repo/location/::`date '+%Y-%m-%d-%H.%M.%S'` location/to/be/backed/up

Backing up over SSH

In all Borg commands we can use ssh://ip.of.server/repo/location/on/server.

borg create -C auto,lzma --progress ssh://my.backup.server/repo/location/::name-of-backup location/to/be/backed/up

Viewing a repos backups

To list all the backups in a repo we can run the following:

borg list /path/to/repo
