I can confirm this bug on my end. It looks like Appwrite is uploading the file twice to the backblaze server.
One is encrypted and the other one isn't.
My backblaze server is located in EU Central and I'm using the default bucket settings:
Encryption: disabled
Files: Private

[JoshiJoshiJoshi]

I had the suspicion that it was also downloading all the files twice. So I tested it by downloading the files through the admin console a few times and it seems to confirm my suspicion. On my end I only received one file but I guess the backblaze adapter is downloading 2 files in the background.

@rossanmol and @JoshiJoshiJoshi, what are your encryption and anti virus settings on the bucket? What are your anti virus settings from the .env file?

[JoshiJoshiJoshi]

@stnguyen90 both settings are enabled in the appwrite console, but the anti virus is actually disabled in the .env file.

Disabling them doesn't make a difference. In fact, if you disable "Encryption" it still uploads two files and one is still encrypted.

@JoshiJoshiJoshi that seems quite odd that it's still encrypted. 👀 Are you sure you clicked on save? Does viewing the bucket JSON show encryption is false?

[JoshiJoshiJoshi]

@stnguyen90 I double checked it before posting it because I found it weird as well 😉

Restarted the docker container and issue still persist.
Tested file types: jpeg, png, pdf, zip, tar.gz

[stnguyen90]

@JoshiJoshiJoshi, actually, I have a feeling it's gzipped rather than encrypted:

appwrite/app/controllers/api/storage.php

Lines 510 to 511 in e658457

	$compressor = new GZIP();
	$data = $compressor->compress($data);

[JoshiJoshiJoshi]

@stnguyen90 doesn't look like I can open it if it's just gzipped

[stnguyen90]

@JoshiJoshiJoshi, did decompress it fail?

[JoshiJoshiJoshi]

@stnguyen90 indeed, none of the files can be decompressed. Besides that, all the files which can't be openend are actually bigger than the actual file, so I kinda doubt it's just gzipped.

@stnguyen90 @everly-gif File Upload/Download initiation and speed is a lot slower compared to other storage adapters. It takes appwrite several seconds to upload a file to Backblaze and download also takes several seconds.
