I’ve noticed several times that backup zip files seem to vary in size in an inconsistent way. For example, I just wrote two more scenes on my current project. I did not delete anything. The previous backup zip, created before the additional scenes, was 647kb; the current zip, with the new scenes, is smaller - 624kb. If I look at my backups (I upload them to cloud storage) the sizes go up and down even though for the most part I’m only adding new content. One zip is 613kb, the next 641, then 624, then 645. Is this normal? I’m concerned that possibly some content is not being saved in the backup zip every time.
A zip backup created about half an hour ago is 650kb; another created 20 minutes later is 625. All that changed between the two was that I added a few dozen words to one scene.
I unpacked the zips so I could compare content side by side. As far as I can tell the content is all good - nothing missing under the *.scrivx/Files directory. However, in the .scrivx/Settings directory the configuration settings file ui.ini shrank from 114kb in the older backup to just 59kb in the later one - and I didn’t make any configuration changes that I’m aware of, just edits to my typescript. When I opened the ui.ini files side by side, I saw a value called “layoutPreview” which is a byte array; this array is significantly bigger in the older file than it is in the newer one, and I think this accounts for the 55k difference in file sizes. So it looks like I needn’t worry that any of my text is not being saved in the backup. Whether a 55k variation in the size of this .ini file between backups represents a bug in Scrivener, I leave to the developers to determine.
