An update on backup integrity: integrity information is now stored in
.backupinfofiles in the remote along side the backups . The file contains sha256 of the backup . For tgz, it's a single hash. For rsync, it contains individual hashes. Further, the backupinfo file is signed using a private key and the signature is stored in Cloudron database. Using this setup, we can verify the authenticity and integrity of backupinfo file (i.e it was created by the Cloudron backup system and was not altered) and we can also check the backups itself are not corrupt using the sha256.While implementing this, I have also added fileCount and size to each of the backup entries. So, you can get an idea of how many files are in the backup and the total aggregated size of an individual backup.
Currently, working on the integrity verifier i.e you can click some button to say "Check integrity" and it will verify the integrity of the backup. This is a bit complicated because you have to download the backup to check the integrity...

Why not have a simpler level 1 integrity light check that is online only, with the file sizes and any files one doesn't need to download for example.
The level 2 deep check is to download and sift through all files.

Yeah, couldn't Level 1 "Check integrity" just essentially be "do the hashes match"? (although presumably they always will otherwise the backup wouldn't be marked as having successfully completed?
)And a Level 2 "Full Integrity Check" (this will take a Long Time as it requires downloading the full back-up to ensure..."
Either way, all sounds like great progress, thanks!

The idea was to check for bitrot and give a good feel about the backup. Just checking the sizes doesn't mean much. AFAIK, file metadata is also stored in different sectors of the disk compared to the real data. So accessing file sizes and them matching doesn't mean much. (For tgz, there is also only one file size to check).

@CBCUN Any minute now..
