I think it is better in that respect to use a windows compression program in windows, like xip, winzip, rar... and send the archive to the backup server, be it it linux or windows based.



Processes don't update FAT tables in general. The kernel FS driver
does that. And I'm sure they have it down pat by now.

Yeah -- for sake of integrity, probably sufficient to limit
to single writers/readers.

Was just thinking of multi-processing cases where one file is
writing/updating the FAT, but another might be reading -- and could get
inconsistent values if the reader read the FAT table in the middle of an
update -- seems like that could cause some unpredictability -- but is
easily avoided if you only allow exclusive access if someone wants to
write it.

It is a non issue, even in windows. Only the operating system writes or reads the fat, even if several processes are writing to files on the same disk - as it is often the case.

Only disk repair or defrag programs have problems with accesing the FAT, they need exclusive access to the disk.
