Based on our experience, the "it would take over a month to restore everything" line is not
is strange as it sounds. A lot of people still use magnetic TAPE to back up. As a 1954 technology,
backup tapes can restore about 1 MB / second, or 86 GB / day. Only 2,600 GB would take a
month.
That's best case perfromance assuming the tech is sitting there the whole time watching closely
and immediately switching tapes and such. A mistake requiring a "do over" doubles the time,
of course.
So it's not unusual for restores to take a long time. I completely believe that, since most backup
systems I've seen have huge problems, and being super slow is a very common problem.
Personally, I'm not fond of living in 1954, so for Clonebox we use 16 drive wide RAID arrays
capable of pushing about 100 times that much throughput. If it would take a month to restore
all of the servers from tape, Clonebox could do it in about eight hours, or the sites could simply
run from the Clonebox servers, which takes only a few minutes to set up.
