Rsync empties out the source folder and makes the disk of the target folder disconnect

Hi,

So I have setup a OMV with a Raspberry Pi 4, with 2 HDD 3,5 inch disks (which have a separate power source) connected via USB

On one disk, I have a shared folder which I called "main". on the other, I have a shared folder called "main_backup"

My goal is to have the data of main replicated to the main_backup folder every once and a while.

So in order to do that I setup a Rsync task, which does what I want (copying from source to destination) every 2 hours.

However, each time the copy starts, as said in the tittle, the source folder main gets emptied out, and the 2nd disk, on which the main_backup is located, gets disconnected (can't see it in the Disk menu in the OMV GUI).

Adapter for the HDD disks I use :

Also, without setting up the Rsync task, everything works fine.

Hope someone can help

Thank you very much for your time

PS : before using the 2 HDD disks, I did the same setup but with 2 USB sticks. The Rsync worked perfectly there...

What does "gets emptied out" mean? That you can't see the data from a client? That you can't see the disk in the GUI? ... I don't understand...

The folder main (source) is now empty (all folders and file are gone), but I can access it

The folder main_backup (destination) is no longer accessible (Windows says it cant access it, giving me the error code 0x80070035) and the OMV GUI no longer show the corresponding disk

I went with the same settings as when I used two usb sticks instead of the disks (and in this case it worked)

I use the defaults settings, nothing fancy

So I've done another testings and this time the source folder is ok and the disk of the target folder got deconnected.

after rebooting, the target folder appeared correctly, and now the rsync job (that runs every 2 hours) seems to work ok.

(didnt change any rsync settings since last time)

that was a weird but seems to work for now

thank you anyway!

Update : nothing works now.

once and a while the Rsync tasks just messes up everything.

so i've simply decided to turn it off and not have a backup anymore, until I can find another software that does a better job

anyway, thank you for your answers

Posting the command and mount points of the disks would help a lot more.

i've run the rsync task manually in the GUI and the error happened (I have to reboot the system in order to see the contents of the source folder)

got the log here : https://imgur.com/a/OiPktAV

here is my rsync config (everything as default, except for the archive mode disabled for a test, but the problem is here even with archive mode on)

as for the disk mount point, I don't know where they show up in the GUI?

Thank you

No offense but rsync is a widely used and very common application. There is very likely a configuration issue as it may happen with any software.

Yes no doubt, I was just intrigued that it worked ok with USB sticks instead of disks, and now doesnt work.
