Backups still not verified or what?

[philkunz]

I thought v9 was to verify backups?

That is kinda shitty tbh, that are still issues like this.

[philkunz]

https://forum.cloudron.io/post/114219 -> Here it is specifically said v9 verifies backups. So is it being done? Or not? Another user posted problems with CIFS. Either way -> I doubt you are verifying backups if this still happens and there is no error otherwise.

Again ProxMox saves the day... Its a bad feeling knowing I can't rely on Cloudron to have my back at the moment.

@philkunz 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 ?

[philkunz]

Wait, you are simply creating a hash? Verification means you create a snapshot of the live filesystem, then actually unpack the tar and check wether that matches, after each backup. Simply saving a hash does nothing.

There is indication now, that CIFS mounts might a have a problem of some sorts.

[philkunz]

My CIFS mount is on a Synology RS2423RP+ rack mounted unit with ECC usinf Btrfs... I doubt that Synology messes up the file with something essential like this, when this is the basic thing they sell to SMEs.

Not at all. Hashing is very well suited for data integrity. Not sure why live snapshots of file system is needed . one two three etc. Plenty of articles to read about this.

I think but for a start we need to know if what Cloudron thinks it saved on the backup disk matches what is currently on the disk. This is what computing a checksum will tell us.

@philkunz also, none of the app backups (i.e backup of other apps) work and not just a specific one, correct? If not, can you please try to clone a couple of other apps, just to rule out some obvious guesses.
