Hi Nick, by default VBR alarms you when datastore has less than 10% of free space. I would suggest to increase datastore so you have 15-20% left. Do you use Veeam ONE? It has a number of capacity planning reports which help to estimate the needed amount based on the performance trends. Thanks!

When I upgraded to 9.5 I started receiving warnings on a number of my virtual machines because Veeam detected the amount of free space being less than 10%. I decreased that to 5% and a lot of the warnings went away, but not all of them. My recommendation would be to add an option so that I can select either a percentage or an amount of actual disk space remaining (it was previously 10 GB). So if I have a very large datastore, say greater than 1 TB, I don't need to have a significant amount of disk space available just so I don't get a warning from Veeam.
My biggest concern is that if this warning is always happening, it will be ignored, which then defeats the purpose of having a warning.
I did open case #02066626 and they said the best way to get the developers to look into this is to post it on the forums.

10% is the official VMware best practice. If you don't care to follow them - you could simply reduce this value to whatever makes sense to you, potentially even down to 1% (which is by an order of magnitude smaller than the best practice)? In fact, setting this value to 1% will let you get warnings at 10GB for a 1TB datastore - just as you had this configured previously.

The primary reason, I believe, it was adjusted with VMware best practice. 10% is much more flexible than the fixed threshold, considering variety of environment sizes (10 GB of free space is way too low for a multi-TB production datastore holding large VMs).

I'm currently managing to migrate from Veeam 7 to Veeam 9.5. I've deployed a second Veeam 9.5 infrastructure next to my existing v7 one and I'm migrating step by step all my jobs.
I've got an issue with one VM: it consists in a VMDK 1,95TB hosted in a 2TB datastore. Despite the low space potentially used for snapshots, the Veeam 7 job performs successfully (the night during minimal usage to limit snapshot size) but on Veeam 9.5: 31/05/2017 03:16:05 :: Production datastore XXXXX is getting low on free space (46.8 GB left), and may run out of free disk space completely due to open snapshots.
How is calculated this minimum requirement? Has it evolved since Veeam 7? Can I bypass this control?

I have this message when i run a backup “Production drive D:\ getting low on free space (199,2 GB left), and may run out free disk space completely due to open snapshots” D: disk there are 724 GB free, I don't understand why job is not running .

You can find it in General Options -> Notifications -> Skip VM processing when free disk space is below, by lowering this parameter the job should start processing. However, I'd recommend you to contact the support team and let them take a look on the issue with the disk space. Thanks!
