@rpm Please check out Data loss - 0 byte files (revisited)
I’m not using an M1 Mac but I don’t think that’s related. My guess and suspicion more and more is that this is a weird iCloud Drive issue. I’m curious if we can get a few more data points from others who’ve hit this blank files issue as to whether they’re also storing their vaults on iCloud.
I am wondering if there’s a tool I can run that will watch a set of files in a very tight loop and quickly pop up an alert if a file gets modified or zeroed by an outside process. Almost like a customized version of an antivirus app.
update Nov 2021: Just want to note that I no longer think this is an iCloud issue, as I moved away from storing my vault on iCloud a long time ago, and am still consistently hitting this data loss issue. It remains a big thorn in my side.
