Error on linux mint

[ts678]

@Breat

you mean the verify files in advanced?

No. That’s a verification, but just one sample of three files, the same as the default after a backup.

@ts678

We’re not sure what shape your other pCloud Drive files are in, but you can survey all your files
as described in neighboring forum topic Error while running Synology backup, on damaged files.

Let me quote a bit:

@ts678

In GUI terms, it means set Command to test, keep the Target URL. Change Commandline arguments either to empty, or a number, or all (which will be slow). You can’t name a specific file, but all will test that one eventually. If you want a specific file, you need to do it the hard way. Download, use some tool.

and you already did the specific file test – next (maybe slow) test is to test everything sometime.
