- Copy all backups from the reFS volume to the temporary disk (If you have used FastClone before, your Backups will be copied with their entire size and not with the space savings from our FastClone feature. This can be an issue for your storage, if you have many synthetic full backups.)
If you had to copy back all files and want to use FastClone again on the reFS volume, an active full backup or backup file compaction is required to use FastClone with manually copied backup files.
Sorry I don't understand these two sentenses
I use "File to tape" Job to backup my files. This is the first time I hear of "FastClone", is this tech similar to copying files in explorer, what's the difference between them?
And do you mean that I should use FastClone to copy my files from reFS volume to a temp drive, then I use FastClone again to copy my files to formatted reFS volume again, so Veeam will recognize the volume and continue using incremental backup to the tape?
If I only use the "copy and paste" function in the explorer, will Veeam recognize: these old files are the ones that have already backed up to the tape?

Before you start with a downgrade, could you please check if you face a similar error like the one from this post?
I haven't installed BitDefender on my computer and there is no problem during creating VSS snapshot in my case, it works fine!
My problem is, while file backuping period, Veeam will say "Task E:\myfile.pdf completed with warning. Details: The volume repair was not successful." and the software just stuck and I had to press the eject button on the tape drive.

Good news! I have found a temporary solution to this problem!
I found that each time I open the file that Veeam can't read, in the next time, the file will not assert error any more and it can be backed up successfully, which means once the file is read, it will become a normal file and won't cause error any more.
So I tried reading every file I want to backup by selecting these files and using 7-zip hash calculate tool, then Veaam can backup these file with no error!
I think maybe Veeam can't process the metadata in reFS 3.9 or MS made some mistakes when upgrading my reFS volume, and opening the file can "refresh" the file state to the normal state.
But this is not the best solution because read all the files are quite time-comsuming, I hope Veeam will fix this small bug
Thanks!
