* The nature of the business, and contents of the backups, can impose some
constraints not for everyone ... let's suppose someone stole the backup
tape ... is there stuff on there that requires the company to tell the
whole world you were data breached?
* We do not use encryption. Plus I have heard tales that if you use
encryption, and develop bad data associated with when the backup tape drive
begins to go flakey, forget about being able to recover your data, so when
we do go to encryption, we will also need to have unencrypted locked up
on-site, so as to protect both against insider crime and outsider.
* We also are on the economy model of backup safety ... thanks to this
thread I think I might write up a document "In case of my death, tell my
landlord that co-workers may enter my home to retrieve off-site backup and
some other work-related stuff."
* I now live 60 miles from our AS/400 and protect backup tapes from hot
weather by wrapping them in change of clothing.
* How close is your home & work in terms of risk of same
disaster? Remember both natural disasters and man made.
* Perhaps a rotation scheme such that the bank safety deposit box has one
save-21, with another at home (protecting against different risks)
* Perhaps the backup tape needs to go in a sealed plastic container, that
will protect it from moisture if the bank vault gets flooded.
* I remember years ago when we used diskette magazines on S/36, carried in
plastic cases 5 magazines per case 10 diskettes per magazine. My boss was
carrying them to the car in winter, slipped fell and discovered that mud
could be injected into the magazines under high pressure of crash into snow
bank. I"m glad it was him & not me, because I often hear about how
expensive backup media is, but human medical is a bit higher.
