Database Operations

Configuration migration and data modification operations.

Hash Algorithm Migration

Warning

• Affects all backup content, it's recommended to make additional data backups
• Migration may take a long time depending on file count and disk IO speed. Migration tasks cannot be interrupted

Migrate the hash algorithm in the database to a new algorithm:

!!pb database migrate_hash_method <new_hash_algorithm>

File Deletion

Delete Files from Backup

Delete specific files from a backup:

!!pb database delete file <backup_id> <file_path>

Example:

!!pb database delete file 59 world/cache/file.txt

Recursive Directory Deletion

Recursively delete a directory and all its contents from a backup:

!!pb database delete file <backup_id> <directory_path> --recursive

Example:

!!pb database delete file 59 world/cache --recursive

Notes:

• Cannot delete the root directory of the backup
• Deleting directories requires the --recursive parameter
• Default requires user confirmation to prevent accidental operation
