nginx access/error logs (and any other per-site log/ dir) change on every request, so they showed up as modified in every single backup - pure noise, no recovery value. Exclude any path containing a log/ directory (re:/log/) from borg create. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
backup-agent
Backup and disaster-recovery tooling for a Linux server: Borg
backing up /home/srv/files/content — including a MariaDB database
running in Docker — with an offsite mirror on Scaleway S3 via rclone.
MariaDB is never stopped during backup: dump_db.sh takes a
transactionally-consistent logical dump (mysqldump --single-transaction)
while the container keeps running, and the container's raw data directory
is excluded from the archive entirely (a .nobackup marker file), so only
the logical dump ever gets backed up. Zero DB downtime.
Components
| File | Purpose |
|---|---|
borg-backup.sh |
Daily backup orchestrator (run from cron): dump → archive → prune → compact → integrity check → offsite sync. |
dump_db.sh |
Per-database mysqldump/mariadb-dump, atomic staging/swap. Invoked by borg-backup.sh. |
restore.sh |
Recovery CLI: full (disaster recovery), db <name> (single database), file <path> (single file/dir), --list-archives. Every mode supports --dry-run. |
Quickstart
# One-time setup, deployment, cron scheduling, day-2 ops, and step-by-step
# recovery for every scenario are all in:
less RUNBOOK.md
Day to day:
./restore.sh --list-archives # what backups exist
./restore.sh full --dry-run # preview a disaster recovery
./restore.sh db <name> --dry-run # preview a single-database restore
./restore.sh file <path> --dest DIR # pull one file out of an archive
Encryption
The Borg repo at /home/srv/files/backups/borg-2025 is unencrypted by
deliberate choice on this deployment — borg-backup.sh will keep printing
a warning about it on every run, which is expected. See RUNBOOK.md if
you want to switch to an encrypted repo.
Requirements
borg, docker, rclone, flock, a mysql/mariadb client — see
REQUIRED_CMDS in borg-backup.sh. Targets Linux; flock(1) doesn't
exist on macOS, so these scripts won't run as-is on a Mac.
