Quicken Backups cause ReadyNAS Backup Jobs to Fail

Thanks for your reply.
Copy from USB to Mac HD works.
Also tested RN pull backup job, from Mac HD to RN... worked without failure. Both this test and original post were completed using SMB connection.
Error in original post occurred on multiple attempts. One attempt showed multiple .QDF-backup files in the error log. Another attempt showed one .QDF-backup file in the error log. Looking at the destination share on the RN, some .QDF-backup files do successfully make it through the RN pull backup job. The failed .QDF-backup files appear on the destination share on the RN, but the file size is much smaller than on the source.

It's hard to conceive of a way that the NAS would trigger a forced eject of a USB drive. The drive is being read by the Mac operating system.
Can you try manually copying the QDF-backup files to the destination share?

Same USB force eject occurred on multiple RN pull backup jobs. Restarting the failed RN backup tends to complete the RN pull backup jobs.
As for your question: Successfully copied the folder and .QDF-backup files using both Finder and RN browser page.
Performed a First Aid check on the USB drive: no issues.
Doing a "pull" backup from a PC where a file may be opened during the backup process is always a risk. You may just get an incoherent copy or no copy of the data, or you could cause a problem with the program/system that has the file open. That's why using a backup program designed for the PC with the NAS as the target is usually better. I'm not familiar with what it's called on a Mac, but I'm sure it has an equivalent to Windows Shadow Copy that is used to create a backup source from an open file that won't cause such problems.

Interesting.
Are you saying the act of a "pull" backup can cause a closed file to be opened during the backup process? (Something like this appears to be referenced on this link: https://community.netgear.com/t5/Nighthawk-WiFi-Routers/ReadyShareVault-clobbers-Quicken-backup/m-p/1936196)
In this case, I do not have the Quicken program currently installed on the Mac to be able to open the file.
Would the Mac alternative to Windows Shadow Copy be Time Machine?
