Not directly relevant for pgbackrest probably, but I noticed that Alpine comes up in a few reports of failing rm -r on CIFS. I think it might be because BSD and GNU rm use fts to buffer pathnames in user space (narrow window), while Alpine uses busybox rm which has a classic readdir()/unlink() loop: https://github.com/brgl/busybox/blob/master/coreutils/rm.c https://github.com/brgl/busybox/blob/master/libbb/remove_file.c As for CIFS, there are lots of reports of this sort of thing from Linux CIFS clients. I am suspicious of the 32 bit monotonic resume_key apparently being used to seek to a starting position. I don't plan to investigate myself, but ... is that even trying to avoid skips and duplicates?
