Veeam error messages

Dear Experts,

I am new to Veeam and have encountered the following message.

Any idea on how to resolve these issues?

1. Failed to finalize guest processing. Details: Failed to process 'TruncateSQLLog' command. Failed to truncate transaction logs for SQL instances: MICROSOFT##WID. Possible reasons: lack of permissions, or transaction log corruption.

2. Failed to create disk digests
Failed to load digests from target.
Error: Target WAN accelerator error: There is not enough space on the disk. Failed to write data to the file [C:\VeeamWAN/VBRCache\FromBackup/3f849499-2811-452b-9f5e-ca8c3ac314c0_bd9888cd-a709-4c2d-ba88-5ac388088d52_D166E831E6F6B0BEE66A7C9C3A195272_trg.blob].

3. Failed to create change tracking time stamp for virtual disk file C:\Hyper-V\HIBDC02\Virtual Hard Disks\HIBDC02_8D33BDE0-BFCA-4693-B4A1-434B0732D0A3.avhdx

I know there is not enough disk space, so where do I free up disk space or is it a setting that I must tweak?

Browse the Storage & look for old log files which can be moved to a local disk, if this doesn't help then you will have to increase storage space for the virtual machine or migrate the VM to a different disk with sufficient disk space.

Went to delete the checkpoints from the Hyper-V manager for some of the non-critical servers.

So got space for now.

But still wish that Veeam has a mechanism to clear out expired replicas to make way for new ones.
