Any way to backup the docker volumes as directory and not in archive?

[akash07k]

Actually I'm using this image since some months now and I must say that it is fantastic!
The only thing which I miss is the incremental backups.
I use Backblaze B2 and hence I require incremental backups a lot.
I'm thinking to pair this image with Kopia because it can make incremental backups.
But I'm unable to identify that how to configure this image so that it doesn't generate the tar archive.
Instead of it it generates the directory and that same directory will be backed up with Kopia because it provides incremental backups.
Any help please?

Right now this is not supported. It should not be too hard to add the functionality though (I'm not entirely sure how the configuration would work right now, but it's very likely it's possible to figure this out).

If anyone wants to add this, I am happy to discuss the implementation details, merge PRs and give support in any way that it's needed.

Till then it can be added, I want to ask that is backing up the volumes directly from /var/lib/docker/volume/(volume_name) a good approach? Obviously, I'll stock the containers before that

I have never tried that so I cannot give any advice.

Another thing you could do is: use this image, and before using Kopia to upload to B2, untar the archive created (you could even do this in a labeled command). This should give you incremental backups as well, it's just not the most efficient way.

Yup, that's a fantastic idea. going to implement this kind of setup soon. Thanks a lot :-)

Hi, is incremental backup something that is as of today in scope or will be anytime soon?

Thank you

Incremental backups would be nice, yes. That being said, I don't know which storage backends would even support this?

As a workaround for now, you can do something like described here https://offen.github.io/docker-volume-backup/how-tos/handle-file-uploads-using-third-party-tools.html
