Re: Back ups with High Availability Web Server

Sure it would be live! You are thinking back up from the production server while users look at the replica. I'm thinking users are on production while backups happen on the replica. This way they see current 24x7.

Remember that there are versions of Mimix for example that don't support rolling back and are less costly. Also if you don't intend for the backup server to ever be live it needn't have the CPW, Memory or Disk arm count of production, just enough to store everything, keep up with replication, and do backups.

Larry,

Ya, I thought of that, and besides the cost it wouldn't work in this case.
As the data always is changing (ie, the documents are always being scanned
in, updated, etc.) So while the web site would be up, there'd be that 18
hour window where the data wouldn't be "100% live"... :) If you know what
I mean.

But, it is so far the best scenario we have come up with. I don't think
SWA would work that well in this case.

Here's a question, when saving large amounts of data, what is the
bottleneck? The saving, the amount of data, or using a tape drive? Ie,
would it be a lot faster to save to a save file and then FTP that data to
an external server?

Well the 'old standby' options are to have a second system with Mimix or
PowerHA or Maxava etc that is replicated to. Do backups there and now
you're up 24x7.

Here's a question I have a customer interested in.

They have a web application that they make available to people during
normal business hours (gov't entity). It's basically looking up old land
records, court cases, etc. Scanned and redacted documents.

They now what to make this available to anyone. You would pay for 24

hour

access (w/ CC), then so much per page of each document you want to save

to

PDF.

The issue they are having is because the number of documents is so large,
the weekly system save they do takes about 18 hours. They do daily

backups

that saves only things that have changed, and takes about 2 hours.

They are trying to figure out the best way to do these weekly system

saves

and still give the customer a good experience. For example, if they sign
up at saturday at 1am for 24 hours and then backups start for 18 hours,
there's trouble. So they're trying to find the best balance between
availability with the safety of the full system backup.

I said since they are doing the saves every night, maybe they could push
their system save to once a month. Then set up a schedule so that if a
user purchased 24 hours close to a backup time, they are warned and their
time extends past the backup.

Any ideas? I'm sure others have dealt with this before. Thanks!
