The two Docker deploy pages now link Backup & Restore where they say "have backups" / "back up both the database and any local assets", and that page's "What to back up" list says that with SQLite the database means memos_prod.db together with its -wal and -shm files, or a .backup copy. Read on its own, "the database" is the one file that on a running instance holds almost nothing (4 KiB against a 160 KiB -wal on a fresh 0.30.0 in my test), and the deploy pages are the ones a Docker user reads. Three lines, no new page.

Addresses usememos/memos#6271.

Too many files changed for review (360 files, 100 file limit).

Bypass the limit by tagging @greptile-apps to review.

Review Change Stack

Walkthrough

The backup checklist now documents SQLite -wal and -shm files and recommends the .backup command for consistent online backups. Docker Compose production notes warn that copying memos_prod.db while Memos runs can omit WAL data. Docker upgrade notes link to the Backup & Restore documentation.

Merge Risk: 🟡 Moderate · up to f70cb

The improved SQLite backup guidance should not merge until its example reliably writes the backup to the documented location; otherwise users may believe they created a recoverable backup when they did not.

The two Docker deploy pages now link Backup & Restore where they say "have backups" / "back up both the database and any local assets", and that page's "What to back up" list says that with SQLite the database means `memos_prod.db` together with its `-wal` and `-shm` files, or a `.backup` copy. Read on its own, "the database" is the one file that on a running instance holds almost nothing (4 KiB against a 160 KiB `-wal` on a fresh 0.30.0 in my test), and the deploy pages are the ones a Docker user reads. Three lines, no new page.

## What to back up

- the database itself
- the database itself - with SQLite, `memos_prod.db` together with its `-wal` and `-shm` files, or a copy made with `.backup` as below; on a running instance the newest rows are in the `-wal` until SQLite checkpoints them

Use a shell-expanded backup destination.

The .backup command receives ~/.memos/memos_backup.db as a literal path because the invoking shell does not expand ~ inside the quoted argument. Use $HOME or an absolute path for the backup destination.
