Module backup

Expand description

Backing up unreadable journal files as .corrupt-* siblings and pruning old backups.

Structs§

BackupId 🔒: Identifies a .corrupt-<millis>-<seq> backup file, ordered by creation time.

Constants§

MAX_BACKUPS 🔒: Number of .corrupt-* backups kept per journal path; older ones are deleted once a new one is created.

Functions§

backup_and_reset 🔒: Renames path aside as a timestamped backup and returns an empty session.
prune_old_backups 🔒: Deletes .corrupt-* backups for path beyond the MAX_BACKUPS most recent, so a repeatedly-failing journal doesn’t accumulate backups forever.
