Is it possible to implement custom backup providers?

I just found https://github.com/yakovkhalinsky/backblaze-b2 which seems active

Yeah it seems fairly active and supported.. So it should be fairly simple to implement a B2 provider, taking the S3 one and adapting for B2, right?
Regarding the box repo, is it possible to maintain a customized clone and use that on a server instead of the official one? I know that such setup can't be officially supported, and can be potentially dangerous, but it can be useful for some advanced customizations or testing of new functionality.

Thx for your support,
P.

@girish Any information if SFTP will become an official backup storage solution? If so, do you have any ETA?
I want to do backups to a Hetzner Storage Box.

@girish @nexbit Any update on Backblaze B2 backup target? If there's a branch with progress I could put some time towards finishing it. I'm also a developer and am eager to have native Backblaze B2 support. The b2 node library and existing backup target interface linked above looks helpfully straight forward.

@fourspace For Hetzner storage box, just mount it via SMB - https://cloudron.io/documentation/backups/#sambacifs

@adrw We haven't worked on the B2 backend. If you want to hack on it, first step is to just create a separate project that implements our storage interface -https://git.cloudron.io/cloudron/box/blob/master/src/storage/interface.js . You can see the other backend providers as to how it's implemented (same directory). I am afraid there are no more docs that the code itself. If we have a standalone project that implements the interface (roughly), it's easier for us to integrate it into cloudron.

@girish Thanks for the path forward, I'll post back when I have some chance to hack on it and get an implemented Backblaze B2 interface working.

@adrw Thanks! You can join our chat if you need any help.

We put in SSHFS/CIFS in 5.3. B2 support is in 5.4

@girish what's the advantage of using the cifs method over filesystem? I've been using hetzner storagebox mounts for months (as fs), what is different when I change to cifs?

[nebulon]

Currently the main advantage is, that it checks if the filesystem is mounted prior starting the backup. This prevents situations where for some reason the mountpoint got unmounted (ie. network errors) and the regular filesystem backup provider would then use that mountpoint, which is now just a regular folder on the / disk, and put the backups there.
Also backup permissions are dealt with a bit differently, since the uid/gid are set with the mount options.

good points, thanks, gonna switch to cifs then!
