Allow backup history to be stored on a server different then the current one

[Ovais Tariq]

Backup history is currently stored on the same server as the one doing the backup. It would be nice if xtrabackup would accept DSN so that the server where backup history is written can be changed. It would be specially useful in the cases where GTID replication is being used, and backup is taken on a slave and we want to write the backup history information to the master.

[Sergei Glushchenko (sergei.glushchenko)]

This is a reasonable request.

[Ovais Tariq (ovais-tariq)]

Is this something that can be looked at. This again prevents the use of the backup history feature, because if I do backups from the slave I would not want to write to slave for obvious operational reasons:
- slaves are read-only
- i don't want to have errant GTIDs
etc

Ovais,

This feature request is having low priority at the moment.
