Inconsistencies after importing database backup

Hi Till,

I think I will put this in a ticket of its own, because it is a new issue.

I just had to do a database backup. After importing, there was some mismatch of the data (some data of the last view hours were like before import and the older ones like the time of the backup, which should be that way).

I cleared the Redis-cache and the reimported backup again and suddenly it worked out.

Is the cache the culprit of this strange behaviour and if yes, do I always have to clear the cache before importing a db-backup?

Thanks a lot in advance,
Johannes
