Mirror Repositories

[riwich]

The Mirror Repositories function in a backup job seems very useful to me. I tested it, but found that the snapshot is actually copied to a second repository, but only the snapshot, not a complete backup.

This seems a bit strange to me, because in this configuration, the mirror repository must remain 100% synchronised with the source from the very first backup onwards. If the mirror fails once, the entire mirror repository is no longer consistent.

Perhaps I have completely misunderstood the function?

Maybe, but from my point of view, this implementation is not useful, at least for me. For me, a mirror repository would always have to be completely synchronised with the source and also be 100% usable for a restore.

I would appreciate your feedback on how you see this, thank you!

@riwich, did you find an answer?

I'm using a local repository as my first stage of backup, and rsync to copy the local repository to another drive on a monthly basis. I'd like to introduce a sync of the local repository to a remote site, and I'm wondering if Mirror Repositories is a good way to do it.

@lyneld, for the offsite copy, I opted not to use a second zerobyte backup job or to use rsync. Instead I used zerobyte mirroring in my backup job(s), despite the concern by @riwich of there being no full backup in the mirror repository. I can't say that I've found the latter to be true. It sure seems like the mirror repository contains a complete backup, but maybe somebody could show me a way to test that assertion.

I can confirm you that on copy to mirror even if it's only the last one the full data will be taken over. You can test this by creating a new local repo and adding it as a mirror. The new repo will be way bigger than your last snapshot on the main repo and you can restore anything from it

Amazing! I fully intend to use the mirror feature rather than having two backup jobs. Will test it out and then set it up. Thank you! And thanks for an amazing project - absolutely love it.

Just wanted to report back - the mirror option works perfectly! And if anyone is wondering (like me, who had no idea how mirror works), the mirrored repo size is pretty much the same as your local repo size.

@nicotsx it would be great to have notifications for mirror jobs, so we know if something failed. And a progress tracker as well. Both would be nice to have features.

@lyneld, I agree with your feature suggestions. I recommend that you check the issues to see if they've already been made, and if not, create one or more new issues as feature requests.
