How much space needs to the allocated for this?

My system wants over 9 GB.

It's an adjustable percentage of your hard drive. Right-click on 'My
Computer' or get to System Properties through Control Panel | System. On
the System Restore tab hit the Settings button. From there you can adjust
it.

Yep...

I'm well aware of that. That's where I got the figure I quoted.

But the question dealt with How Much Is Enough -- Not Where To Find It.

Thank You Kindly.

One or two GB is usually sufficient for most people.

Right.

80 GB hard drive.

12% is also correct.

How much space does a restore point take and how far down from 12% can one
safely go?

I generally only keep the most recent restore point unless I'm doing lots of
upgrading.

If there was a set size per restore point, it would be easy to multiply
that by the maximum number of desired restore points. Unfortunately, the
size of a single restore point varies from system to system. Also, the data
stored is chained - instead of copying everything for every restore point
changes are noted in smaller restore points. In other words, restoring to a
newer restore point is likely to draw on more system restore records than
an older restore point.

Personally, I have restricted this tool to 1GB and only allow monitoring of
the system partition which holds Windows and main applications. I usually
have about 4 to 6 weeks of restore points available. In my opinion, that's
more than "enough" for System Restore as I wouldn't rollback to anything
older than 30 days. System Restore is considered a short term recovery
tool. For problems that may have "older" roots, I would restore an image
created with True Image instead of using System Restore.

I arrived at the 1 GB figure by experimenting. Started with the minimum of
200MB. If I had a day with a lot of system and driver updates, more restore
points were made and more space used. Consequently, the time frame covered
by that batch of restore points was quite short. Things probably would have
been "okay" at 500MB but bumped up to 1GB instead.

Thank you kindly.

That was a very intelligent answer.

What bothers me is I don't know when a Restore Point is being made or how
much space it is taking.

We need a gauge of some sort for that in Windows.

Come back in a few days and see what's available.

Adjust as needed.

Today ras_nb commented courteously on the subject at hand

On my PC, before Windows cleans up the older RPs, it has taken
up maybe 20%, compared to the max 12% I am allowing. I know
better than to manually delete any (now, thankfully I didn't
messs things up earlier!), but I know no way of shrinking the HD
space without deleting the whole bunch and starting over (by
turning RP off, then back on again). In my case, it ain't a
biggie, as my primary partition still has 36 gig left. Dunno
about space remaining for the OP...

Today Ken Blake, MVP commented courteously on the subject at
hand

Ken, I thought that changing the RP setting up or down causes XP
to delete the whole pile and start over. I just said it ain't no
biggie for me, but your comment caused me to re-think that.
Probably 3/4 of mine are more than a month old. I should cut
back, I just don't want to risk losing the last week's worth.

I'm certainly not hurting for space on the primary hard drive -- I'm only
using 16% and more than 63 GB remains free.

I can also easily back up to 160 GB on an external hard drive -- as
required.

I just don't like ash and trash on my system.

Ignore the Build Up of detritus and it will soon be costing you in
performance and flexibility.

But one needs to prune judiciously -- and constantly.

Well, DSH, that's one thing I agree with.

I have 57% of my 40GB drive used. But I don't like having useless stuff
there. And 40GB is not a lot anyway. You appear to have twice that amount
and many out there have lots more.

I have partly eased the space problem by installiing a 250GB extrernal
drive, shared with a laptop, but this is certainly *not* going to be filled
with garbage.

Perhaps we have similar personality types :-))

Supposedly a restore point is made every 24 hours but I've found that this
can fail if the system is not on for many hours each day. There can be
large gaps between the dates if counting on this automatic process alone.

Most programs and drivers that utilize the Windows Installer create a
restore point before making any changes to the system. Example: Windows
Updates that include an uninstall option usually create a restore point
before installing.

You can create a restore point at any time manually. Using this method, you
know that a restore point being created. I usually take the few extra
minutes before installing a new program or a new driver to do this. It's a
simple matter of clicking Start> Help and Support> System Restore> Create a
Restore Point.

Yes, I've been doing that ever since I got this new system.

I don't like the software doing something such as creating a Restore Point
without TELLING me what it is doing.

If a Restore Point is created I should get a message telling me that -- OR
much better -- I should have the option of saying "Yes, do it now" or "NO,
not now."

It varies.



I don't think a percentage is the right way to look at it. It's the total
amount that counts. As I suggested in my message quoted below, 1-2GB should
be sufficient. That should give you at least two weeks worth or restore
points, and more than is seldom of any use.



Then you're throwing away lots of valuable protection. Don't keep a lot,
but keep more than one. As I said, I recommend keeping two weeks worth.

The XP OS is not set up to easily keep two weeks of restore points and
delete the older ones. Yes, I know it can be done manually.

It simply asks whether the operator wants to delete all but the most recent
restore point.

If the Best Professional Advice is to keep two weeks of Restore Points then
the OS should be configured to permit that with a setting and the click of
a button.

Windows does it for your benefit.. if Windows was to report everything that
it did, you would get a constant stream of 'can I -can't I' messages, some
for which you may not immediately have an answer..

Re. Sytem Restore space, Windows defaults to 12% allocated space for any
drive size over 4Gb, but even that is not written in stone.. if the drive
fills up to where there is no longer 12% available freely, System Restore
loses its space allocation, and starts to delete the older restore points in
order to set new ones..

Where are these Restore Points stored in Windows?

The XP OS is not set up to easily keep two weeks of restore points and
delete the older ones. Yes, I know it can be done manually.

Correction: I was wrong about that. Only ALL but the most recent Restore
Point can be deleted. One can't easily just keep "two weeks worth".

Hobson's Choice.

UNSAT...

The menu simply asks whether the operator wants to delete all but the most
recent restore point.

If the Best Professional Advice is to keep TWO WEEKS of Restore Points then
the OS should be configured to permit that with a setting and the click of a

Off the point.

I didn't say "everything that it did".

I said:

"I don't like the software doing something such as creating a Restore Point
without TELLING me what it is doing."

The OS SHOULD request permission to do that.

[80 GB. 63 GB free.]

That sounds sensible.

So, one resets the slider to allow 2 GB of Restore Points instead of 9 or 10
GB.

But I would PREFER the ability to delete the Restore Points INDIVIDUALLY and
DISCRETELY -- line item veto -- after a week or two, when everything is
running smoothly.

NOT Hobson's Choice.

Microsoft keeps dumbing down the OS -- and that's a Bad Show.
