Ah, I forgot I had this problem before: https://www.mail-archive.com/[email protected]/msg135224.html I tend to think now it's the disk space. This was a Monday morning dump, when the /backup is "most full" with the previous week's dumps.[0-6]. I rm(1) them before doing the fresh dump, but that space probably only becomes available a bit later due to softdeps (I think). I will see whether it happens other then Mondays. Thanks for the hints.
