We have recently switched from BE2012 to Veeam 6.
The reasons we switched:
1. Unreliable backups for a Windows 2000R2 Hyper-V Cluster. We would change nothing, and BE would randomly fail. Tried all the fixes and patches, with only minor improvement. We had BE from 2010 onwards, and this behaviour never improved. They never really placed many resources into improving Hyper-V CSV backups, often giving customers the promise of "we haven't forgotten about Hyper-V customers, improvements around the corner" - these promises were lip service.
2. BE 2012 is buggy, and they didn't listen to their customers. Read this thread for hundreds of complaints from current customers: http://www.symantec.com/connect/forums/ ... pexec-2012
3. Very expensive. You need to purchase a separate agent license per SQL database/instance. Very greedy IMHO, why not make it one license per server?
I tried Altaro Hyper-V backup, and found it way too simplistic and limiting. You had to run the Altaro front end on a Hyper-V host, and the product didn't support software compression (their answer to that seems to be "turn on NTFS compression on the backup drive"!!). It was cheap to buy though.
As for Veeam..
- From day one of trialling it, it was been rock solid reliable without any failures. I can even perform a live migration of a VM while it is being backed up, and Veeam will keep working. BE would fail for us in this circumstance.
- It has a simple interface (yet has a lot of technology under the hood). BE is complex. They have tried to fix it with BE2012, but some of the most basic things are still hard to find.
- Licensing is very simple. Whereas BE licensing is complicated.
Veeam doesn't get away scott free though...
- It would be nice if it could write to tape (not a complaint, just a wish)
- I have a feeling they charge Aussie customers more than US customers for the product. In my calculations, it cost around $US320 extra per socket for the Enterprise edition, all up an extra $US2,500 for 8 sockets, just for being Australian! Very unfair IMHO. We couldn't afford this extra hit, so we went for Veeam Standard. I Believe there is going to be a senate inquiry in the parliament about software companies charging Aussies so much more.
