Data Recovery after failed upgrade from Owncloud v9

Last year I upgraded my owncloud server from v9.1.6 to v10.0.2, and somehow completely botched the upgrade process. The storage had server-side encryption enabled, and upon starting the new service I was given a series of prompts. The end-result being that the content was moved to files_trashbin, and the data for my owncloud user folders was empty.

Sorry for being vague. All of the encrypted data for the two users was moved to files_trashbin in the Owncloud data folder, and I want to know if there is any way to decrypt, or add these files back into Owncloud.

There are 1000’s of photos that we lost, so please help!

There are different types of encryption in ownCloud (master key vs. user key). Not sure what was available at the time of 9.1.6…

Usually the server post template asks for a whole lot more information which you neglected to provide.

Not sure what your current status is and how you would like to proceed. Without the additional information it is going to be close to impossible to help you at all.
