Retrieving encrypted metadata backups

[bbonvi]

Hello.
I assume if the file system volume uses an encryption, so do the metadata auto backups under the /meta folder. Is this correct? In this case, how do i decrypt them back? I can't use gzip -d on .json.gz file since it gives me Input/output error and of course i can't use juicefs load.

Hi All, I'm also trying to figure out how to decrypt the metadata dumps. This is a hurdle to be able to use juicefs, as I need to test backup retrieval.

Looking at the code, it seems to just call object_store.Put, which in the case of an encrypted object store, means the key to decrypt is put in the database, meaning the decryption is impossible??? Hopefully I understand this incorrectly.

Could a symmetrical encryption of these dump files with the encryption key be performed? Then the user just needs to backup the encryption key, and everything else is taken care of.

We can't do that easily even you have the encryption key, will fix it soon.
