There are a lot of tags that seem fairly redundant. There are a number of posts (example) discussing data remanence and recovery which seem to be used more or less interchangeably:

What should we do about this? Is there one particular tag we should use for questions involving data remaining on non-volatile storage media and proper techniques to ensure the data is unrecoverable?

Easy things first: The fourth tag, , is just to broad and should be burninated. Most questions can be retagged with or .

The tags and are sides of the same coint - a coin that is called . How these three should be structured is a tricky question.

I see three possibilities:

I would prefer #1 or #2.

    I don't think #1 is good because data-recovery could refer to, say, breaking encryption after data is lost, whereas data-remanence is about the physics behind data staying around after being overwritten.

  • @forest Would that objection also mean that #2 is bad? Perhaps questions like that needs to be retagged with encryption or decryption or similar?

  • While I can appreciate the desire to optimize the tags, many people asking questions, searching, or following do not have the technical expertise to know some of the terms are redundant. Unless it's causing a real problem, I suggest #1 - leave as is. May 2, 2021 at 15:51
