Error message backing up to NAS

[jacobacci]

I am trying to back up files from my PC (mapped local drive W:\) to a shared folder on my Synology DS1815+.
Windows native file copy is off.
Could this be a permissions issue?

Hi, does it work if you enable the option:
Copy directly to destination file (do not use a temporary file)

'copy directly' seems to work without issues. Strange

[TGRMN Software]

It seems there is an issue with renaming the temp file on the NAS during the copy...

So it seems. Any idea what could be reason for this?
When I was using EXT4 on the NAS, I did not have the issue. Now I am using BTRFS

[TGRMN Software]

Can you manually create

\\?\UNC\192.168.0.10\music_other\Musik von David\1312\Classical\Dvorák\String Quartets Op.61 & 96 American (Calliope) - Quatuor Talich\~vv1.tmp

with some text in it, and then rename it into:

\\?\UNC\192.168.0.10\music_other\Musik von David\1312\Classical\Dvorák\String Quartets Op.61 & 96 American (Calliope) - Quatuor Talich\04-String Quartet No.12 in F, O.flac

With and without \\?\UNC\ prefix, it could be an issue with \\?\UNC\ ?

Interesting result: I created two target directories on the PC and on the NAS. I then copied the files with VV, getting the same error messages as before:

I then clicked 'continue and ignore all errors'. After the process ran through with several error messages I went to the NAS and lo and behold, the files were there. Not any temp files, but the flacs

I tried to post a link to two screenshots, but it seems external links are not allowed

On my second NAS (DS1910+, also BTRFS), the error does not occur.

[TGRMN Software]

Could it be an issue with the NAS firmware for the NAS which has the issue?

The issue is only on one NAS and only in one shared folder. I have deleted and recreated the shared folder. The issue persists.
We are unlikely to find the cause for this issue. I will simply use 'copy without temp file' for this folder going forward. Luckily is a folder I don't sync often.

OK, thank you
