Active Full During Production?

Veeam Logoby rm4g00 » Mon Aug 08, 2016 6:15 am

Hello all,

Does anyone know any issues in an active full backup during production hours? our main file servers & mail servers took much longer to complete active full's than normal this week :roll: so now they are still completing holding up the chain...

Other than the expected performance issues would there be any pitfalls/major issues in office hours?

Thanks

Hi,
it depends on the hardware you have for your production storage, some may have a huge decrease in performance, some would have a lot less. Classic vmware snapshots have indeed some performance impact regardless the storage in use, because of the I/O redirection that is used there. There's not to much that can be done to this technology, but some workarounds can be applied:
- the quickest one is to switch from active full to synthetics, so that your weekly fulls take the same time of an incremental
- upgrade to vsphere 6 plus patches to limit the impact of snapshot consolidation (http://www.virtualtothecore.com/en/vsph ... hing-past/)
- again with vsphere 6, look at VVOLs if your storage supports them, as the snapshot technology is totally different and has no performance impact
- if you have a supported storage, use Veeam backups from storage snapshot, as the vm snapshot is removed after a few seconds from the beginning of the job, not at the end, so it doens't matter how long it takes for the backup to complete

Thanks mate- vsphere 6 is in the pipeline - synthetics is what we have been thinking of implementing then just a normal active full monthly.

Would you recommend a synthetic full every week then an active full last sunday of the month - just incase?

Sounds like a good idea, indeed. Also, running periodic Surebackup Jobs would not harm. Thanks.
