fix(backup): keep backups working on odd names and record accurate metadata - #36
Conversation
…tadata Follow-ups from the review of #34: - A file whose name holds a backslash, CR or LF no longer fails every backup. It is reported and left out of the checksum inventory (the archive CRC still covers it). - Accept every Compose service name Compose allows (leading ".", "_" or "-") when recording images and when pairing them for --fresh. - Record the MariaDB 12 dump tool version (its header has no "Distrib"), and record only the version number for MySQL and older MariaDB headers. - For SQLite, record the host sqlite3 as the snapshot tool instead of presenting it as the panel's database server version. - Pass the SQLite path and database credentials to write_backup_runtime instead of reading them from the caller's scope. - Restrict the restored .env and Compose file to their owner as soon as they are restored, not only after the services start. - Docs: MySQL/MariaDB dumps use the default table locks, not one transaction snapshot; drop the "consistent" claim for SQL dumps.
WalkthroughThe backup scripts now record database-tool metadata, skip unsupported filenames in checksum inventories, and accept additional Compose service-name prefixes. Restore scripts validate the expanded service-name set and harden restored ChangesBackup and restore behavior

A rabbit checks the backup list,
Then sniffs the files that should be missed.
New versions hop into the log,
Restored secrets hide from fog.
“All tested,” says the rabbit, pleased.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Correct the write-delay claim in both guides. Default dump locks apply per database. In a multi-database dump, panel writes can resume after the panel database’s locks are released, before the full dump ends. (mariadb.com)
