"Well my son, life is like a beanstalk, isn't it?"
Hello and thanks to all of you!
The Windows product I am referring to is Sonicwall CDP:
http://www.sonicwall.com/us/products/backup_and_recovery.html
Pretty amazing kit.
Maybe, I have looked at the product and it is the kind
of product you *have* to use when using operating systems
like Windows. And still you do not get the same level
of shadowing that VMS Host Base Shadowing gives you.

From the data on the site above, it's not clear if you get
a complete shadow copy of the system disk. It looks as if
you have to point-n-click on som e GUI to setup which
directories and files you want to be handled by this product.
You can't just say "shadow disk X to disk Y", right ?

And versioning of files are a totaly different beast. Note
that VMS does that out-of-the-box for you per default.

And what databases are running on these systems ? If you are
using Rdb I would never let some product like the one on the
link backup or shadow my database. Rdb has all the tools
needed to do this in a safe and supported way.

The only reason that the product on the link above exist
at all, is that Windows is realy bad on this fields.

It also seems that you have to buy some special boxes
to use this product. It's not just something you install
on your systems, right ?

I think you have to better specify what kind of backup
(or whatever) you want before asking for solutions for VMS.
VMS is a system where many of this questions was solved
20-30 years ago in the design of the operating system itself.

You just can't take what you know about Windows and try
to implement that on VMS.



Box is an Alpha server, other box is Itanium...WAN link yet to be
sized but initial data set is 200GB then I just want to do
incrementals.
What kind of "data" are these 200 MB ?
Plain files ? Rdb or Oracle database ?

For plain files, VMS BACKUP has all/most tools you need
for both total and incremental backup.

For Rdb, RMU ("Rdb Management Utility") has everything you
need for total and incremental backup of the database (the
only supprted way, b.t.w).

For Oracle there are other tools, I guess...



45K quid is just high, compared to anything as far as we are
concerned. Having built trading rooms, I know what this project
deserves in terms of funding and 45K would be a lot better spent
elsewhere, like something like a 100MB ethernet site to site link!!

The Sonicwall device uses a separate software product (Acronis?) in
addition to its own 'agent' software running on covered PCs to
optionally image the drive(s) to the CDP. You then choose which
folders (and subfolders...) are monitored for changed files; each time
a file is changed its supposed to have a copy pulled by the CDP and
stored there. You are not supposed to select folders containing data
stores for exchange, sqlserver, etc. There are separate 'application
servers' for exchange, sqlserver, maybe others, that work through
those product's APIs to make copies of the databases/data stores on a
scheduled basis to the CDP. Essentially like using the database (or
other) backup tools to make the copy, excepts its pulled to the CDP
via the network. These should be consistent.

We've used these server backups to recover from a couple of instances
of exchange puking all over itself, as well as sql server defecating
on its databases.

I don't think you can have the application data stores backed up for
every change; its scheduled only; the folders and files get the
'continuous' protection. On the applications you can do
'differential' and 'log' backups instead of fulls and have them run
hourly, daily, whatever.

I don't know of a commercial equivalent on VMS. You can get better
capabilities for the commercial databases and such, with backups and
journal data shadowed 'offsite' (or by other means), and of course if
you allow it you can retain multiple versions of actual files on disk
instead of sideline CDP storage. Depends on needs.



There used to be a product called IIRC DFS (?) DECnet File System.
for file sharing between VMS systems
Anyone have a better memory than me?
