backup drive time

yesterday when i tried to restore a drive with SP there was a surprise,
almost everyone in this forum recommend it for its speed.
thats what i got when i restored a drive.It took just 1 minute 19 sec to restore my 20 gb drive.
Its a big surprise for me because ATI other well known program use to take 20 minutes to restore the same drive.
I dont know how SP restored that drive in that much time but the drive is in good condition and no problems noticed.
any one got lesser time than this?

 

sach1000rt,

Could I ask how large was the image?
How long did it take to create the image?
How much data is in the partition? (How much Used Space)
Where was the image stored? Another HD? Internal or external?


Thanks.

 

No way.

 

I was doing it gently.

 

thats why i called it a surprise. here are the details

20 gb partition, which has around 5 gb of data, made snapshot with SP and it created that in 1 min 40 sec , its size was around 1 gb.i saved it in same HDD but different partition.

 

That compression is quite unbelievable.Here using Ghost 2003 to image my slimmed down install of Vista Ultimate containg 2.5 gig of data the image comes in at around 1.3 gig using the fast compression method.

What size is the pagefile on your drive as I don't think that is backed up with the other data.Not sure on that though?

 

pagefile size is 2gb. excluding that it may come around 2.7gb to 3gb.
SP snapshot size is around 900mb to 930mb.

 

I always thought SP is better all over,but that much surprised even me.

 

DS is actuley the fastest in RESTORE same speed as SP in backup

 

I have no experience with DS but it can be,imaging has also to do with reliability,ease of use,hardware support and vendor support,with SP you can't get any better.

 

sach1000rt,

It's sounding better but is still not what most people experience. Especially with writing an image to the same HD. Writing to a second HD is twice as fast which would make your image time 40 seconds. Does the image verify without errors?

Do you have a hibernation file?

We're trying to find out how much data was actually imaged. I can create an image of my second WinXP partition in 25 seconds but I regard that as normal, considering the amount of data.

 

Correction... It was my restore time that was 25 seconds. The imaging time was 40 seconds.

 

Assuming he used standard compression-the actual size that is relevant here,is the image size being used.

So his speed is quite ordinary.

Of course it depends on how powerful your computer is.

In my case,I am achieving 3gb/min backups and about 2.0 gbs/min restore,so would have achieved a 1 gb restore in about 30 -45 seconds actual restore time -that is after the restore started in SP.

 

Do you have a hibernation file?

No i dont have hibernation file.

yes i did the backup with standard compression method.

"Especially with writing an image to the same HD. Writing to a second HD is twice as fast which would make your image time 40 seconds. Does the image verify without errors?"

is that right?

 

Hairy Coo,

I haven't used SP for a while but compressing 2.7gb to 3gb of data down to a 900 MB image doesn't sound right to me. Too much compression for Standard compression. What do you think?

Its good as long as the snapshot works well.
I restored that snapshot 2 days before and there are no problems till now.
I thought it was the right size for standard compression.
But still its lesser than the snapshot which i made with acronis with maximum compression.
I will not worry as long as it works well for me.
All im happy right now is within a minute i can restore my system now compared to acronis which used to take approx. 20-25 minutes, in that time one can install fresh xp also.

 

sach1000rt,

Could you try this. Open My Computer with the Folder bar down the left. In the left pane select the C: drive and click Properties. What is the Used Space?

Now go to the right pane which should show all the C: drive Files and Folders. Select them all and click Properties. What is the Size On Disk?

Thanks.

 

Brian-after cutting away all the irrelevant info-sachs is just doing a standard restore rather slowly.
Nothing worth commenting upon really
I could equally say I am restoring my 320gb partition in less than one minute-sounds impressive doesnt it-but the image size is only 2.2 gb , and so on.
I'm not confusing the issue by saying that prior to compression the system partition to be backed up contained 6.6gb of material

The recommended Standard compression works perfectly well and to my knowledge has never been queried,-why should we start now??

Same ratio as mine! Never had the slightest reason to query it.

The only critical info required when measuring SP performance,by and large is the image size and of course the computers power comes into it.

I think the best advice is sachs should just keep on the way he is going-everything seems quite normal- dont try to improve on a successful formula.

 

Hairy Coo,

The SP userguide says..

That was my experience when I used SP. 40% compression. But sach1000rt is getting 70% compression on his figures. Don't you think that is strange? To me it suggests he is not backing up 3 GB of data.

Do you have an explanation? Does SP omit any data apart from the page-file and hibernation file?

i know what u r trying to tell.
i dont use hibernation so there is no hibernation file.
pagefile size is 2gb.
right now i cant tell the size of c drive as i installed many softwares so it cant be compared to the pricise size of that snapshot.

im not worried about the compression, size of snapshot or anything else,
why am i surprised is that acronis took 20 min approx. or so to restore same drive same size.but SP took 1 min 19 sec.
it is indeed surprise for me.

 

I understand. Could you check those figures for us when you do your next backup image,

Yes, 20 minutes for a 1 GB image is not right.

 

Sachs-SP is faster than ATI,but not by that much.
This once again illustrates that SP is more reliable and can power its way through just about anything,whereas other backup apps are more temperamental and can be thrown off course for whatever reason.

That is exactly the reason I gave up TI 10.
