I am sending the backup logs by smtp to me,
but it is cumbersome to have a review how the backup jobs of the last week/month for a special VM were performed.
Would it be possible to have a local log (eg. in xsi-dir/var/log) per backupjob-id or better per job-description?

Well, you already have all that you need to easily arrange something like that. Let us know what your exact goal is and we can prepare some post on the subject which will for sure be interesting to other people.
You can exchange keys with any kind of server and log that info to a Mysql server, to some Syslog server, with which we already offer comatibility, etc...
