I took my huge project, and again attempted to back it up with Scrivener (Using File -> Back Up ->Back Up Now…).
The resulting archive is 30 MB larger than any of the prior two tests (on V19 & 20). However, the “backup file” contains errors, and is likely unusable.
Here’s a screen shot from 7zip’s archive test:
Further, the zip file SHOULD be near 5.33 GB in size, not 4.1 GB.
In addition, while the “backup” was occurring, I happened to monitor Windows’ Temp directory and Task Manager, and some process was writing a 0 byte file there, and during those writes it’s writing to disk (monitored in Task Manager)(filename: “jet” followed by 4 hexadecimal characters, “.tmp”).
Scriv also evidently writes other “jet” files, all empty: Jet1.tmp, jet2.tmp, jet3.tmp. jet3 appeared when the archive was 90% done or so.
Also, randomly during the backup process, the little progress dialog window disappears completely, and then, some dozens of seconds later, reappears.
I ran the thing a second time, and this time, it produced NO output. NO file.
I know the devs replaced the zip algorithm, but it’s still broken for large (>4GB) output files.
