I ended up fixing my database issue by copying the data from one
database to another... so that's fixed but now I'm being asked how we
can prevent this from happening in the future.

What happened: one of the members of a RAID 5 array died.  The rebuild
worked fine but when it was done we had lost one little-used database
(restored from an old backup) and had the structure of 5 tables in
another get corrupted (two of them happened to be Sysindexes and
sysobjects).

The owners are asking me to theorize as to why this happened and what
can be done to prevent it from impacting us as badly as it did this
time.  I'm at a loss as to what to suggest - I know enough about
server hardware and backup solutions to use what we have and be
dangerous beyond that.

Does anyone have any suggestions for what to include?

I know that the hardware needs to be replaced; the server is 5 years
old!  I'm wondering if there is a service not unlike Carbonite that
can provide historical backup services for upwards of a week or two of
either the BAK or MDF files.

For our backups right now we have Symantec Backup Exec System Recovery
that takes an image of each drive on week-nights, then a different
process that copies the backup files to a removable USB hard drive.
These drives then get swapped out on a daily basis.  The reason we got
in to the "pickle" that we did was because by the time we discovered
the failures we had already cycled through 3 days which meant any good
backup was overwritten.

Yeah, it sucks having to go through this but it's definitely been a
learning experience!

Until Later!
