The `resolved_ts` in the filename indicates the backup progress, meaning that data before this TSO has been fully backed up.

However, note that this TSO only reflects the progress of certain shards. - `global_checkpoint`: represents the global backup progress. It records the latest point in time to which data can be restored using `br restore point`. - `{date}/{hour}`: stores backup data for the corresponding date and hour. When cleaning up storage, always use `br log truncate` instead of manually deleting data. This is because the metadata references the data in this directory, and manual deletion might lead to restore failures or data inconsistencies after restore.
