I have used Bacula for many years, since version 5. In the past, I have
mentioned my two Nas's along with various Windows and Linux machines get
backed up on a nightly basis to tape. Currently that tape drive is an
LTO3 based drive. Some of the older backups are on LTO2 tapes. My tape
drive is starting to show its age, and within a period of time it will
have to be replaced. (Since I am a retired programmer on a fixed income,
cost, as always becomes an issue.) I need to understand the backward
capabilities of more recent drives. How high could I go with LTO based
machines while still maintaining the ability to read (and hopefully
write) those old LTO2 tapes?
Thank you everyone for your help.
All anyone could ever want to know about LTO tapes:
<https://en.wikipedia.org/wiki/Linear_Tape-Open>.
The rule of thumb is read two back, and write one, but that changed with
LTO-8. Sort of. Sigh. Read the wikipedia page.
Cheers,
