I'm facing a situation when veeam tries to take a snapshot of the vm in order to initiate the backup, it gives me the following message: "File is larger than the maximum size supported by datastore" as I've read on the solutions, there are 3 options, listed below. I may try to move the snapshot to a different datastore with a bigger block size, does anyone have any experience with this error?
There are 3 ways to remedy this:
If you do not want to back this disk up, you can set the disk that is too large for the datastore to "Independent" on the settings of the VM. Right-click the VM, click Edit Settings, click Change disk to Independent. After that the disk needs to be excluded from the job. This will make it so VMware does not take a snapshot of the disk anymore, as Independent disks are not supported by snapshots.
You may want to move the machine to storage with a bigger block size.
You may want to edit the VMX file, so that snapshots will be created on a different datastore that has a bigger block size. Refer to the knowledge base link below for further details:
