Re: Disaster Recovery

[Darrell A Martin <DMartin@xxxxxxxxxxxxx>]

Greetings:

I send a copy of the overnight incremental backup tape to our satellite 
warehouse each morning in an anti-static bag (because we discard dozens of 
those every day) to be stashed in a sturdy waterproof box. This is in 
addition to the weekly data, and monthly full system, backups which are 
held by our commercial off-site backup storage vendor. The incremental 
tapes are rotated weekly. Our data loss risk should our main facility be 
suddenly and totally wiped out is therefore:

        until 8:00 a.m. - can lose changes back to previous day at 1:00 
a.m.
        after 8:00 a.m. - can lose changes back to today at 1:00 a.m.

The satellite warehouse is 0.9 miles away. If both buildings were 
similarly situated in Canada, they would be about 1.5 kilometres apart. If 
a small asteroid hits between them we will have some difficulties keeping 
the business going.
