[dba-Tech] Backup redux

You just can not have too many backups. And it's a good idea to have
multiple forms of media involved. When I was in a mainstream IT
Mainframe operations environment we kept daily, weekly and monthly
backups and kept 30 daily, a dozen weekly and 2 years worth of monthly
backups of our data and maybe disk images too. Some of those got
rotated offsite every week. 9 track reel to reel tapes were relatively
cheap though. We spent at least 12 hours a week doing backups.
I just bought an external 5 TB Seagate drive at Costco yesterday. Cost
$135 as I recall. Plan to back up all my systems including music and
photos to that.
I also have a Thermaltake hard drive docking station that allows me to
swap regular sata hard drives so I can rotate several to do
generational backups. It connects via an ESATA connection and so runs
at about regular hard drive speed.
It all works well. When I remember to use it. That is the downfall.
