Time to copy a Snapshot

[Antarctica]

I just want to know if it is normal that it took 1h 38 min. to copy a snapshot of 5.40Gb to a external USB Harddrive???

Thanks

[ErikAlbert]

1h38m is way too slow, even absurd.
Can't you give more details of the hardware ?

[wilbertnl]

Are you using a USB 1.1 or USB 2.0 connection?

[Peter2150]

It wasn't USB 1.1 by chance. That might account for it.

Well, I know my PC is not of the last generation...

It's a AMD 1800+1.56 GHz and with 512 Meg of Ram.

Peter2150, yes I am still using USB 1.1.:-[

As a possible point of reference, it takes FD, as it is installed on my machine, about 1.4 hours to copy a 14+ Gigabyte snapshot to my internal hard drive. This is roughly three times the size of your snapshot. As a matter of fact I just made a snapshot today.

My system is several years old, too. I have a Pentium 4 processor, 2.05 megahertz, and 512 megabytes of ram. This may or may not be within the generally acceptable range for FD. I don't know. But, for what it's worth, I give you these stats.

Now I understand why it's so slow. No further comments, because I don't want to hurt your feelings. :)

If you have USB 1.1, then it's faster to transfer huge data over wired lan. In case that is an option, of course.

Thanks to everyone for your comments:)

I am planning to get a new system at the end of the year or next year. So in the mean time I can live with this slow speed problem, I'm not exporting or importing snapshot every day.:P

I'm no hardware expert but I think you can get USB2 PCI cards quite cheap. Might be a useful stop gap until the end of the year

Takes me 9-12 minutes to copy (totally create a new Snapshot) about 4.5-5.0 gig, but that is to another internal drive. :-\

If you can disconnect from the internet and then turn off your av that should speed up the snapshot creation considerably. I am making snapshots of 19gb on this machine and with av on it takes about fourty minutes and with av off it takes about twenty five minutes. This is a very fast computer but it even makes a difference on this one. It's worth a try.

Good point. I always disable my AV when doing any copying with FDISR

You understood me very well. That was exactly what I wanted to say. ;D
But waiting as long as possible to buy a new computer is also good.
My new computer is already out-of-date, only the components are new.

FYI, according my Seagate External Harddisk Manual, the theoretical speeds are :
USB 1.1 = 12 Mbits/sec
USB 2.0 = 480 Mbits/sec
FireWire= 400 Mbits/sec

As you can see there is a huge difference between USB 1.1 and USB 2.0 and is probably the main reason why it lasted 1h38m on your computer.

Thanks bigc73524 and all the others for your help and comment. I'll give it a try with disconnect the Internet and AV turn off.

I will let you know.:)

I do exactly the same thing as bigc, but there is a difference.
1. BigC disconnect the internet and turns off AV.
2. I boot to a snapshot that has no internet, no security softwares, no internet-related softwares, like email, browsers, etc.
In that special snapshot, I create most of my snapshots.

It might be a good idea to make a note in the new snapshot description to remind you the AV is turned off!

Had an opportunity to do a timing. Times clearly depend on hardware. I created a new snapshot from an archive on a 2nd internal drive.

Snapshot size was 9.5Gb. Time was 7 minutes with transfer rates up to 24580 KB/sec

My transfer rate was 1215 KB/sec.:-[ It's definitly time to change my system.8)
It should be done in the next two month, hopefully.

I'll time it to USB later. Difference between new box and old box is unreal. Old box wasn't a slouch either.

Time to create and external snapshot on a USB 2.0 drive was 15:27 minutes. About twice the internal drive

Creating archived snapshots on an external harddisk takes longer, but refreshing them is a matter of seconds or a few minutes.

Frankly I'm not impressed by USB 2.0 at all, I thought it would work faster, but it doesn't bother me.

O.K.I test it with my present system, disconnect Internet and turn off KIS and BoClean. It took 1h12 mn instead of 1h38 mn, so I would say about 20% speed increase.:P

Well, 26 minutes less is quite an improvement considering the circumstances. Computers are really fast. Aren't they ? ::) ;D

Hé ErikAlbert, 26 minutes gives me enough time to drink a beer.:P ;D
