## What Document that `gpbackup` cannot start more than one backup within the same second. - `sys-utilities/gpbackup.md`: add a paragraph in the Description section explaining the one-second timestamp granularity, the resulting error message, and how to avoid it. - `sys-admin/backup-and-restore/perform-full-backup-and-restore.md`: add a tip under "Filter by schema" for scripts that back up schemas one by one. Both `docs/` and `versioned_docs/version-2.x/` are updated. ## Why The backup timestamp (`YYYYMMDDHHMMSS`) is the unique backup ID and also names the backup directory and lock file. When a script runs `gpbackup` repeatedly and two runs start in the same second, the later one fails with: ``` [CRITICAL]:-A backup with timestamp ... is already in progress. Wait 1 second and try the backup again. ``` This is an architectural limitation rather than a bug, as discussed in apache/cloudberry#1714.
