I have trawled the forum for this already but can only find references to questions around this on Veeam 7, so here goes...
We have a new Veeam 9 server deployed with the latest updates. This is used the complete reverse incremental backups for a couple of different VMware clusters, with each clusters backup data going to different repositories. This is all working fine and as expected.
We then have tape jobs run once the backups complete. Each tape job copies the cluster backup repository to a set of tapes.
We run a 4 week cycle of tapes where tapes get changed daily and are off-sited.
On the tape side of things we have (right now) an IBM TS3200 48 slot library with 2x LTO3 heads.
We are just in the process of ordering HP 2024 libraries with 2x LTO6 heads to replace the old IBM library.
So right now, I would like to proof of concept what we want to achieve with the IBM kit before the new toys turn up.
I would like to use both heads to complete EACH copy to tape job so that we get this completing sooner.
Im aware that I can run 1 job on 1 head and another on the other at the same time, however That's not what I want.
I want to reduce the time taken to complete the tape archive by using both heads for the same job at the same time.
Is anyone able to advise is this is possible and how to configure it?
I also have an issue where Veeams handling of tape libraries is very basic so Im not able to fill 1 magazine with Cluster 1 tapes, and magazine 2 with Cluster 2 tapes. Are there any recommendations around how best to handle this?
I have tested partitioning the library, which then presents as 2x Libraries in Veeam, which addresses part of this, however this has the result of assigning 1x head to each partition statically so I still cant do 2 head backups.
Finally, is there any way of configuring Veeam to pick tapes sequentially, as I cant work out how to have it re-use tapes in the same order each cycle.
e.g. if I fill magazine slots 1-8 with tapes, Veeam uses slots in order 7,3,5,2,8,1,4,6. This is causing concerns around labelling of tapes.
I am quite disappointed with this behaviour. It would be helpful if Veeam could use tapes in sequence.
On a separate note I am having very regular issues with Veeam in the middle of completing copy to tape jobs, where Veeam looses the inventory information from the library and aborts the backup job.
Im seeing this at least 2-3 times a week at present and is very frustrating, as well as impacting us as a business putting our tape backups at risk.
The library is configured in accordance with Veeam recommendations, latest firmware, latest IBM drivers applied in Windows, listed correctly in Device Manager, drivers are non-exclusive mode etc.
Thanks for any helpful input.
