Restic

Restic is nice command line application to backup and restore your data.

I have chosen restic years ago because:

  1. It works on windows.
  2. It has plenty of supported targets that can be “dummy” storages (S3, SSH connected drive…)
  3. Works nicely out of the box and I can understand circa how
  4. Encrypts backup

I am currently using this to back up to Hetzner S3 Compatible storage:

#!/bin/bash

export AWS_ACCESS_KEY_ID=[XXX]
export AWS_SECRET_ACCESS_KEY=[YYY]

# this is repo initialization
#restic -r s3:https://fsn1.your-objectstorage.com/[BUCKET] init

# mounting, this mostly end with error, that it is already mounted
mount /mnt/Pool

# backup
restic -r s3:https://fsn1.your-objectstorage.com/[BUCKET] --password-file=[PATH_TO_REPO_PASSWORD] --verbose \
backup /mnt/Pool/Gold

# remove old snapshots
restic -r s3:https://fsn1.your-objectstorage.com/[BUCKET] --password-file=[PATH_TO_REPO_PASSWORD] --verbose \
forget --keep-last=60 --keep-daily=60 --keep-weekly=60 --keep-monthly=60 --keep-yearly=60 --prune

and this to back up to my NAS:

#!/bin/bash

mount /media/Cedar

#restic -r /media/Cedar/[BACKUP_NAME] init

mount /mnt/Pool


#restic -r /media/Cedar/[BACKUP_NAME] --password-file=[PATH_TO_REPO_PASSWORD] --verbose \
# snapshots

restic --r /media/Cedar/[BACKUP_NAME] --password-file=[PATH_TO_REPO_PASSWORD] --verbose \
backup /mnt/Pool/Gold

restic --r /media/Cedar/[BACKUP_NAME] --password-file=[PATH_TO_REPO_PASSWORD] --verbose \
backup /mnt/Pool/Silver

restic -r /media/Cedar/[BACKUP_NAME] --password-file=[PATH_TO_REPO_PASSWORD] --verbose \
forget --keep-last=60 --keep-daily=60 --keep-weekly=60 --keep-monthly=60 --keep-yearly=60 --prune

Restic does not schedule anything, so I have those commands running three times per day trough crontab.
