rsync - Jul 2022 - Does rsync verify its writes?

Hello. Does rsync verify its writes?

Re, 'info rsync'.

Maybe I just being stupid, but there's no mention of verification in the
'DESCRIPTION' section, so
despite the words in the 'OPTIONS' section, '-c, --checksum'
topic (which I may be misinterpreting),
I assume rsync does not verify except for the checksum directive.

I admit that I'm paranoid. ;-) ...Please clarify.

Regards, and Thanks,
Mark Filipak.

Rsync does not verify writes.  --checksum doesn't verify anything. 
Sounds like you want a file verification tool.  The simplest would be 
md5sum.

Hi,

you can use the switch --fsync to verify the transfer. From the manpage:

--fsync
 ????????????? Cause the receiving side to fsync each finished file.
This may slow down the transfer, but can help to
 ????????????? provide peace of mind when updating critical files.
