A week ago I started getting the Windows Backup error 0x807800B4, stating "Volumes larger than 2088958 megabytes cannot be protected." I'm not sure what this is referring to. My system volume is a 256gb SSD and the drive all my data is on is a 3TB hard disk. The consumed space is only a couple hundred gigabytes.
I'm backing up over the network to a 6tb SMB volume. I've been running Windows Backup on this machine successfully for a couple months and this started happening with no hardware change. Any help would be appreciated.
