Continuing the discussion from Restore incremental backups v1.5 OSS:
I found the above recipe when looking for a scheme for incremental backups. For the most part it made sense to me as a relative newcomer.
It also makes sense to our use case because we have to perform incremental backups from a lot of installations to a central one - and this way forced us to let the client nodes do a backup but not write it to the central database - it feels like it should be more secure that way - the central database can load the backup safely.
However, we need to add an additional tag while this sideloading is done. To me, this line
SELECT * INTO dbname..:MEASUREMENT FROM /.*/ GROUP BY * makes no syntactic sense - so I couldn’t even figure out to add a tag (denoting which client it was picked up from).
It would be great if someone can link to the part of the documentation where this syntax is explained (I have failed till now) – and maybe suggest how to add a tag.
