  1. Does the external USB drive have anything to do with Retrospect? (Such as being part of a disk backup set.) Otherwise I have no idea. Sorry. I never experienced this problem myself.
  2. Where are the Mac files stored? On an internal (fast) SSD? Or an external (slow) mechanical drive? What do you backup? Just the film files? Or all files? Mac OS consists of many thousands of tiny files, which takes (much) longer time than a few large files (if the total amount of bytes is the same). Have you considered disk-to-disk-to-tape backups?
  3. I'm thinking it's the usual confusion between GiB and GB. https://www.gbmb.org/gib-to-gb Retrospect uses GiB. 791GiB is 850GB (rounded slightly) How many bytes are your storage? 850,000,000,000 bytes?
  4. I would not trust backup software that is not officially supported.
  5. Yes, the documentation often leaves much to desire. For many years you could only select one snapshot in step 5 and then wait (often) several minutes before the next one could be forgotten.
  6. One way is discussed here: https://www.retrospect.com/en/documentation/user_guide/win/management#managing-backup-sets More specifically:
  7. What does the log say? How do you start the restore? Using the wizard or advanced mode? Restoring to a new folder? (This would create a new folder at the root level, named the same as the backup set.)
  8. My guess is that Retrospect isn't run as administrator or run as a user without enough permissions. It isn't clear if you run the backup once or twice a week and it happens every time. Or you run every night and it happens sometimes.
  9. Your scripts will not be affected. Probably you don't even have to enter your license code again. (But keep it handy just in case.)
  10. I would uninstall Retrospect, restart the computer and re-install Retrospect.
  11. It looks like Retrospect is trying to exit the program, but can't. Tried restarting the computer?
  12. Did you just update the Retrospect version? Which version are you running? Did you (or your customers) just update the OS on the Retrospect server computer (or the client's computers)? (I mean something must have changed for this error to suddenly appear). What type of media are you using?
  13. The answer to question 1 is probably "source speed" as outlined here: https://www.retrospect.com/au/support/kb/tape_capacity_faq Your NAS is probably not fast enough to saturate the tape drive, resulting in empty sectors on the tape. Now, question 2 is trickier. It looks like the PC is having trouble communication with the tape drive/loader. Maybe a new driver for the interface was installed on the PC that doesn't work properly?
  14. That has been a feature request for a long time, but I don't think it has been fulfilled yet.
  15. "Chain broken" might indicate a problem with the source disk. A file consists of a chain of clusters (or sectors). If a cluster (or sector) doesn't point to a valid "next" cluster, the chain is broken. Try running CHKDSK on the C-drive.
