After installation of version ’ 22.214.171.124_canary_2017-10-01’ I’m receiving the following error:
Backend verification failed, attempting automatic cleanup
System.ArgumentException: Object must be a root directory ("C:\") or a drive letter ("C").

The destination is an UNC in the format \\\SERVER\Path.
It sound like you upgraded from something to 126.96.36.199 - if so, what version were you on before and how did you upgrade (in-app upgrade feature or manual download and install)?
Also, if possible can you provide the settings for the job that’s failing as a “Export as commandline…” (be sure to remove any personal data you might not want to share such as user name, password, finger hash, etc.).
Thanks for the commandline export - that all looks OK to me (ignoring likely re-formatting issues like the triple-dash before send-mail-url).
It looks like the argument exception may be a common problem with 188.8.131.52 - if you can’t wait until we hear from @kenkendk you might want to consider downgrading to 184.108.40.206, which seems to have worked for some people.
Out of curiosity, does it work any better if you change “C:\Work\” to “C:\Work\” (just add another slash after the colon)?
Thanks for the answer, I’ll roll back to version *.8
About the quote, I’m fairly sure the problem isn’t in the source part but in the destination, as I said I have another backup just like this one, but pointing to a local drive and folder and it works fine.
I have another one, with different sources sent to DropBox and it also works fine.
Nevertheless I made the change and started, the result is the same.
