Restic

Homepage

Restic is a foss tool for managing incremental file backups across multiple computers.

Configuring Restic

Create a location for your backup. I like BackBlaze although they are US based (your data is encrypted with AES-256)

Create a restic env file .resticenv

export RESTIC_REPOSITORY="b2:<bucketname>:<appname>"
export B2_ACCOUNT_KEY=<your_account_key>
export B2_ACCOUNT_ID=<your_account_id>
export PWFILE=/path/to/your/resticpw

Create the file pointed to from PWFILE and add your restic encryption password

#!/bin/bash
 
source /abs/path/to/.resticenv
 
RESTIC=/mnt/user/appdata/restic/bin/restic
 
echo "create mysql backup"
 
/usr/local/bin/docker-compose -f /mnt/user/Docker/wiki/docker-compose.yml run db_bak /bin/bash /backup/mysql_backup.sh
  
echo "back up mysql dump and wiki files"
 
${RESTIC} -p ${PWFILE} backup /mnt/user/Docker/wiki/backup/backup.sql /mnt/user/Docker/wiki/config
 
  
${RESTIC} forget \
    --keep-daily 30 \
    --keep-monthly 12 \
    --keep-yearly 10 \
    -p ${PWFILE}
