Greptile Summary

This PR adds --exclude='volume-backups/' to the rsync command in runWebServerBackup, preventing potentially large Docker volume backup files from bloating web server backups. The change is a minimal, targeted fix for issue #3971.

Key changes:

• packages/server/src/utils/backups/web-server.ts: Excludes volume-backups/ from rsync during web server backup.

Issues found:

• The exclude pattern 'volume-backups/' is not anchored to the rsync source root. Using '/volume-backups/' (with a leading /) would be more precise, though the current version works correctly given the known directory structure.
• More importantly, the corresponding restore function (restoreWebServerBackup) performs a blanket rm -rf "${BASE_PATH}/"* to clear the destination before restoring. Since volume-backups/ is now excluded from the backup, any existing volume backups will be permanently deleted during a restore and will not be recovered. The restore logic should be updated to preserve volume-backups/ across the restore operation.

Confidence Score: 2/5

• The backup exclusion is correct, but the restore counterpart has a data-loss risk that should be addressed before merging.
• The rsync change itself is correct and harmless. However, by excluding volume-backups/ from backups without updating the restore logic, any user who restores a web server backup will silently lose all their Docker volume backups — the restore wipes BASE_PATH entirely before copying files back, and since volume-backups/ is no longer in the archive, it is never restored.
• packages/server/src/utils/restore/web-server.ts — the blanket rm -rf "${BASE_PATH}/"* will destroy volume-backups/ during restore since it is no longer included in backups.

Anchor the exclude pattern to source root

The pattern --exclude='volume-backups/' will match a directory named volume-backups/ at any depth within BASE_PATH. While this works correctly today since volume-backups/ only exists at the top level of BASE_PATH, using a leading / anchors the pattern to the rsync source root and is more precise:

Suggested change

	`rsync -a --ignore-errors --no-specials --no-devices --exclude='volume-backups/' ${BASE_PATH}/ ${tempDir}/filesystem/`,
	`rsync -a --ignore-errors --no-specials --no-devices --exclude='/volume-backups/' ${BASE_PATH}/ ${tempDir}/filesystem/`,

Restore wipes volume-backups not included in backup

Now that volume-backups/ is excluded from the web server backup, the corresponding restore operation in packages/server/src/utils/restore/web-server.ts will permanently destroy all volume backups during a restore. The restore code (line 56) does:

await execAsync(`rm -rf "${BASE_PATH}/"*`);

This blanket deletion removes ${BASE_PATH}/volume-backups/, but since the directory is no longer included in the backup, it is never restored. Any volume backups present at the time of restoration will be silently lost.

Consider updating the restore logic to preserve volume-backups/ by moving it aside before wiping BASE_PATH and placing it back afterwards, or by using a targeted delete that skips volume-backups/:

// Delete everything except volume-backups
await execAsync(`find "${BASE_PATH}" -maxdepth 1 -mindepth 1 ! -name 'volume-backups' -exec rm -rf {} +`);
