Restoring Backups fails

@philkunz said in Restoring Backups fails:

Seems like other people had the same problem before. For me everything runs on Zen 4c infra with ecc, zfs...

Is ZFS supported now?

[philkunz]

zfs is on the host. cloudron uses non-cow inside the vm.

Experiencing the same issue with CIFS mounts. Creating backups work seamlessly. When you go to restore it attempts to restore a small subset of files 3 times before displaying the error. I noticed when I go to restore the app it doesn't prompt for an encryption password, perhaps an internal issue with storing of the encryption hash?

@dylightful Which provider are you using to backup files? What version of Cloudron are you using?

[dylightful]

@p44

CIFS Mount to storage provider - Version 9.0.13

Backups work fine, restoration gives the above error.

@dylightful the verification signature is now saved but there is no UI yet .

Can you check if you have a .backupinfo file next to your .tar.gz ? Inside .backupinfo there will be a sha256 checksum. Can you check if sha256 sum matches with the .tar.gz file ?

@dylightfu That is the main problem.... the restoration, not the backup... Can you give us storage provider company name?

[dylightful]

@p44

It is to a self hosted SAN

@dylightful if there's a setup where we can debug, would be great since we are unable to reproduce it .

[p44]

@dylightful ok. it could be useful to follow @joseph advice, to try to reproduce issue...

I had the same problem with Hetzner Storage Box via CIFS mount...

[dylightful]

@p44 tried hetzner now too. Same issue - backups fine, unable to restore (20GB LAMP stack)

[p44]

@dylightful Please share logs or other infos with @joseph so we can finally understand what’s going on... this is a very important problem to understand ASAP. I had this problem too.

@dylightful If we can have access to your setup, can you write to me at support@cloudron.io ? Would love to debug and figure out why it's failing . Is this reproducible easily - meaning if you take a backup and restore, it fails?
