I only buy used drives. The money I save from buying and using them is more than enough to backup everything multiple times. I personally think a new drive but only one back up is not safe.
Other thought, if you want to be seriously safe about your backup you should put it at your parents house or work in case something happens to yours.
But the thing I keep coming to is the cold backup. How can you keep cold backups over several hard drives, without an entire second server to do the work?
You could just plug them into your server or computer and move them there. Also, a server doesn’t need to be expensive. You could just buy a used optiplex for 40$.
I searched and searched about this and every response of theirs I found gave the same speech about IMAP not being as safe as their apps.
