Check if you get big memory spikes when transferring, or OOM entries in dmesg.

Had some trouble with a new samba install on Debian causing OOM issues recently (this was admittedly in LXC). Resulted in files apparently transfered but were not. This was due to optimistic locks, which are apparently poorly implemented (according to the 2-year old open bug) but on by default. I haven’t done due diligence to say what’s the best solution, I just turned oplocks off.

Who’s going to peer review that?

This means it’s working.

Guys you’re all wrong.

It’s PornHub.

Media failure isn’t the only reason to back up. If you delete a file on a RAID array, it’s gone on all disks. If you need to recover that deleted file, you can’t recover from RAID. The same goes for formatting/damage of the file system, recovery from something wrong inside a database, etc.

I think you mean my data.

Yes.
