@kev-cao I applied the proposed changes to v24.3 + v25.1 with the removal of the old syntax — is that correct? Or, does the change need to apply to other versions? |

| If you back up to a destination already containing a [full backup]({% link {{ page.version.version }}/take-full-and-incremental-backups.md %}#full-backups), an [incremental backup]({% link {{ page.version.version }}/take-full-and-incremental-backups.md %}#incremental-backups) will be appended to the full backup in a subdirectory. To take a locality-aware incremental backup and restore from it successfully, you must maintain the same storage URI and `COCKROACH_LOCALITY` mappings that were established by the corresponding full backup. Alternatively, take another full backup with the matching localities and URIs before running the incremental backup. | |||

I think there was some confusion/ambiguity with my answer in Slack. The incremental mappings don't have to match the full backup mappings, they just have to be consistent. So if with one BACKUP command you have incremental_location = ('foo?region=us-east', 'bar?region=us-west', 'baz?region=us-central'), then that mapping must be maintained for all incrementals in that chain. @dt if you could confirm this behavior that'd be helpful!

Hey @kev-cao, are you only to referring to incremental_location in your comment here? Or, all incrementals? I haven't changed the text for the incremental_location option on this page. This update is only referring to regular incrementals — so I want to check whether I need to adjust the edits I've made or not.
Fixes DOC-12344
Adjust the sentence in v24.3 + v25.1 regarding locality-aware incremental backups to clarify that the the storage URI + the
COCKROACH_LOCALITYregion must match the related full backup.
