RE: Free copy of Lindows

["Ian Lowe" <ian@xxxxxxx>]

It actually only stores the delta information (ie, what has changed) and
an allocation of 10% of the disk covers it. NTFS is transactional, like
a SQL database, and this simply records the previous value of any disk
sector that changes in the compressed delta area. To go "back in
time"
you produce a virtual view of the current folder, minus delta changes..
clever stuff.

I currently have about 6gb of Delta data, and that seems to handle our
(quite busy) office.

In operation, it's pretty noddy - you go to a folder or share, right
click properties, then select the "previous versions" tab - it
lists all
of the time points, and you can "view" or "restore"...
view opens up a
"my computer" view of that folder or file.

You can then copy the older version of the file forward in time.

Compaq used to sell this software for a serious bucket of cash, so I'm
super impressed to have it in a low-end server.

OK -getting 2003 server is not a problem - but will space be ?

Assuming you have 64 save points, is that 64 x data on hard disk, i.e.
big
??

And how simple is it to use, do you need to be MCSE to use it ?

Well, having lost a ridiculous amount of data on a Linux server...
yes.

If you have access to Windows Server 2003, volume shadow copies are
the
absolute mutt's nuts - the absolute last word in getting your data
back.

Since my Linux disaster (basically, down to an immature driver that
stopped a RAID 5 set from working as intended) I have switched across
to
Win2k3, using shadow volume copies, I can step back in time to 64
previous save points, spanning (in my case) 32 days, and recover whole
folders, single files, etc..

I also have all of the disks in my server mirrored in software (and
have
pulled on and plugged it into another PC to check that it can be
recovered.

On top of that, I backup everything to a USB2 External HDD using a
scheduled windows backup.

Short version - What you need is a reliable backup!!

My own view is that Linux has it's place, as a very reliable OS in
terms
of *uptime* but if you actually fancy getting your data back from a
hardware crash, use Windows - either way, if you don't have a regular
(and tested) backup, you will (like me) deserve everything you get.

Ps> BACKUP!
