Also, if they do delete it from "current db," they likely have years of backups. I find it difficult to believe someone like FB (or any other) would unarchive multiple terrabyte archives from storage, restore them (db, etc), delete the data, and rearchive them, for each daily/weekly/monthly/yearly backup my data is contained within.
- charleslmunger 4y agoI have no knowledge of how Facebook or anybody else does their backup deletion - but one way to accomplish this is to encrypt parts of the backups with a per user key, and delete the key when deletion is requested - tapes (or whatever) stay in cold storage but the data is irretrievable.
