Issue with rsync from unraid to Dela Copy server (Windows)

[relink]

I have been reading up on rsync for weeks now, and im still not sure whats going wrong. I am trying to backup a user share called "backup" to a Delta Copy server running on Windows 10.

 

rsync –av --delete /mnt/user/Backup rsync://172.17.89.106:/Serverus/KVM

above is the line im running, and when i try to run it I get;

rsync: --delete does not work without --recursive (-r) or --dirs (-d).

even though nearly every rsync article I have found uses;

-a --delete

so if I change it to;

-ar --delete

I get a syntax error. And finally below is the output if I change it to;

-a -r -v --delete

 rsync –a -r -v --delete /mnt/user/Backup rsync://172.17.89.106:/Serverus/KVM
sending incremental file list
rsync: link_stat "/root/–a" failed: No such file or directory (2)

However the weird part is that it does seem to be copying over the data...But considering that is is backing up critical data I don't want to just assume that's it working. something doesn't seem right and its more than likely something obvious.

i wonder if you maybe at some point in the past you have accidentally created a symbolic link called "-a" which points to a non-existent file/directory in the stuff you are trying to copy.

no i havent, I just created this share a few days ago. I use this folder for backing up my VMs using this script, and that's all that it currently in that share.

anyone? I keep googling and googling ive read the man page for rsync at least 10 times now and i still cant figure this out.

Are you sure  you are running real a real rsync binary?

What does "which rsync" say?

What does "rsync --version" say?

 

Because it behaves as if it doesn't understand the -a (archive) parameter.

 

And -a is just a short form of  -rlptgoD which means that -a implies -r - the parameter it complained was missing for handling --delete.

 

Maybe the problem is that the other side - DeltaCopy - doesn't understand -a.

Have you tried to replace -a with -rlptgoD and seen if the program then will run as expected?

"which rsync" returned

/usr/bin/rsync

and "rsync --version" returned

I tried re-running the command as you suggested, one with "--delete" and another without, below is the output of both.

 rsync -rlptgoD --delete /mnt/user/Backup rsync://172.17.89.106:/Serverus/KVM

Are you doing a cut-and-paste or are you manually entering the commands?

 

Because the following printout seems to indicate the existence of additional characters between "o" and "D":

rsync: -rlptgo\#357\#273\#277D: unknown option

ive done it both ways. same output either way.
