hi I have some Workstations, Laptops, Servers, Refrigerators ;-) ... all backup to a single Tape Drive. Of course I want concurrent Jobs, working fine. However, Maximum Concurrent Jobs has to be set greater than 1 for the Storage.
I also have some Hosts who are served by the same Director but every one of them has its own storage daemon. Maximum Concurrent Jobs is set to 1 for those Storage Daemons. Now I add a machine with multiple virtual machines running. On this Host i dont want concurrent Jobs killing the machine because of I/ O of course. My first approach was to assign priorities. Laptop X -> Priority 10 Server X -> Priority 10 External Host X -> Priority 10 Refrigerator X -> ? Virtual Machine A -> Priority 40 Virtual Machine B -> Priority 41 ... All Jobs are scheduled for the same time, so the Normal Order of is 1) all Laptops, server, External Hosts, and of course the Fridges 2) Virtual Machine A 3) Virtual Machine B 4) ... Last Weekend: I went to a, well, call it recreational weekend. Friday Night Virtual Machine X called for another Volume. i was absent of course. Saturday Night it was still calling for that volume blocking all other Jobs, even the Priority 10 Jobs (although many of them are using other Storage). I now configured Allow Mixed Priority = yes But of course thats a one way ticket. Virtual Machines can not block other Backups now (because Virtual Machines are of priority > 10) but it is theoretically possible that a Waiting Priority 10 Job is blocking the Backup of the Virtual Machines. How to avoid this ? Can I serialize a group of Jobs without setting Priority ? -- best regards, markus ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
