I'm currently unable to backup my USB drive to my home PC. Since I've been having issues where the backup seems to just hang, I had tried selecting a subset of the files on my USB, i.e. just the PortableApps folder (granted, it's fairly big considering all of the email stored in Thunderbird). According to the log, the job ran for 6:03 minutes. The last lines that appear in the log, prior to the time elapsed, are:
The volume for a file has been externally altered so that the opened file is no longer valid.
The conditions are:
PC OS is Windows 10
C: drive to which backup is being done has plenty of free space.
No other PortableApps apps are being run at the time.
Toucan version is 3.1.4
The backup works fine when I use it on my work PC. Any ideas as to what this error means, and how to fix it?
