Hi Phil,
Since you asked for bad backup stories ...
In the mid '80s, I was working at the Canadian head office of a
multinational food company.
We were using 6250 BPI Tapes on STK 4520 drives. My boss, who also
managed operations,
decided that when tapes would get physical errors, the operator

In the early 70's I had a client -- large insurance company -- that was running
DOS on a 360/50. At some point they lost a 2314 volume. When they restored from
backup the restored volume was unusable. Investigation revealed that for some
reason lost in the fog of time the sysprog who had set up

It's actually much more complex than that. Here's a little-known

not happen on an MVS system, but some other vendor's system with those

Does it protect you from ransomware? It gets you back to a good backup.
It depends on how often you backup - and having ransomware means you might
lose all changes since the last backup so unless the database is read only
- you are likely to lose some data.

Also there are various solutions for immutable backups of z/OS data, which
would protect you against ransomware.

Hi all.
We are studying to build the tertiary backup. In fact, is it possible to
hack the VSAM dataset during online period, is there any policy to protect
VSAM datasets ?
