How to sync webDAV via rsync?

Question

linux

I'm trying to synchronize the local folder and the [email protected] I bought a business account in order to have regular access to webdav, mounted it

https://webdav.cloud.mail.ru /cloud davfs user,rw 0 0

I tried many options for keys for rsync, as a result, the least errors when using

rsync -r --size-only /hdd/test/ /cloud/test/  --temp-dir=/tmp --no-owner --no-group

[email protected]:/hdd/test# rsync -r --size-only /hdd/test/ /cloud/test/  --temp-dir=/tmp --no-owner --no-group
rsync: open "/cloud/test/IMGP9973.JPG": Invalid argument (22)
rsync: copy "/tmp/IMGP9973.JPG.p7aPQl" -> "IMGP9973.JPG": Invalid argument (22)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1183) [sender=3.1.1]

It seems to me that rsync is trying to do something that davfs does not allow, but I can't figure out what.

Answer 1

In my case, it was necessary to specify use_locks 0 in the davfs2 configuration. I did not understand if this is a feature of mail.ru or rsync.

Answer 2

because rsync makes a temporary file during transfer in the form /tmp/IMGP9973.JPG.p7aPQl which the remote host doesn't understand
try
--inplace In this case, rsync will not create a new file when copying and then replace the old one with it, but will immediately start overwriting the old file. Such an algorithm will not be able to preserve the integrity of the file in the event of a connection failure between computers, except when used in conjunction with the --backup option.
This option is useful when copying files on a single computer, or when copying large files with block-level changes or data appended to the end of the file.
The option includes --partial (breaking the connection does not delete the file), but conflicts with --partial-dir and --delay-updates
