Backup FROM WebDAV?


#1

Hi,

simple question: is it possible to backup FROM a WebDAV-Storage to some other e.g. local disc?

Hello @bzdega and welcome to the forum!

If you mean can Duplicati directly use Storage Type of WebDAV as Source Data, then I don’t think it can, however if there is a way to access the underlying storage in some way that looks like files, there might be.

Alternatively, perhaps you could use a helper like WebDAV in rclone to clone to local storage for a backup.

Duplicati has support for many protocols (including WebDAV and rclone) for destination but not for source.

If you map a drive letter to your WebDAV storage, you can add source files and folders from that drive letter in Duplicati.

I’ve tried it by mapping a drive letter to my OneDrive for Business storage and was able to backup some files and folders. It’s quite slow, but it works.

Thanks! I started wondering if this was using third-party software, but it looks like Windows comes with it, e.g.

Accessing WebDAV with Windows

and (assuming time stamps work) seems good enough to make it look like files, thus keeping Duplicati happy. Running as Tray Icon rather than Windows service might be necessary, in order to get to this new drive letter.

Just because it hasn’t been mentioned here I’d like to provide some performance advice.

If you can back up locally on the device hosting the WebDAV, do so. It will perform much better :slight_smile:

There is nothing wrong with mounting in remote resources and backing them up, but Duplicati isn’t designed for it so the decision should be made with open eyes about performance penalties.
