How long do major companies keep back ups? It seems like all of these companies that keep getting hit with ransomware Only have last weeks back up laying around. Why can’t you go back eight months? True the data is going to be lacking, but at least the structure is going to be there. I completely understand that a Trojan or a virus can get locked into a back up and it just keeps getting backed up, but if you go far enough back you will find a clean copy.
- SV_BubbleTime 5y agoI have yearly backups for three years. Right now, we could use one of those. At my last place, they only kept 1 year and monthly, but the problem was it was hundreds of terabytes of data on lots of VMs. We tried to restore backups and it was going to take longer than the long weekend just for file transfer. I don’t know what normal process is, but I believe I saw file locker Trojan that didn’t hit every byte of the drive; but rather crawled the file system and did a bit on every file header for speed. So I imagine it’s still faster to pay and fix than restore from backups for some.
- underseacables 5y agoThe company I work for does nightly back ups and we keep them for five years in cold storage. Our CTO got hit with an attack years ago that almost cost him his job at another company, and he vowed to never let it happen again. Are we unusual for this?
