Our customer has very old backups, 20 or more years.
Those where done with WINRAR and winzip of those days.
there are two issues.
1. Are we able to read those formats today ? Or are we supposed to, lets say, every 5 years convert those backup files to latest formats?
Is there any software that will do that for us automatically? Auto update itself and auto migrate the backup files to the new format ?
2. The second point is the storage device, usb connections improve they get faster and better, devices need drivers updated, according to new versions of OS
So I guess we have no choice than to move all every 5 years to new devices ?
HOw reliable would it be if we store in the Cloud? and is it advisable only the cloud ?
How are companies doing this around the world ?
