Back up speeds and sdav

[tigertheboo]

I'm compulsive and backup up to everything attached to my machine).
I have desktop (sdav protected), laptop (sdavprotected), wife's desktop (other malware protected) and two auxiliary hard drives attached to my desktop

For the most part i back up small files so don't notice the time.

But recently I've had to copy a still small 42 meg file with 214 pdf documents. When I back it up to the attached auxiliary hard drive it takes 5-10 seconds. However, when I back it up to the two other computers on my network it takes about a minute and half. (and this slowdown only happened after the upgrade to version 7)

Everyone once in a while I backup my full 5 plus gig main document folder between machines. Depending on the machines it can take up to half an hour but no more. However, at the rate the 43 meg backs up it might take several hours

Has anyone had any experience i backing up large directors between sdav protected machines or can pct comment on this concern.

thanks

I'll give this a test and will get back to you.

Thanks for looking into this.
The folder that was backing up slowly was a new folder being copied to the two other machines one protected by sdav and one protected by other security ware.

Today, I was copying an older (and smaller folder 12 meg about 40 files) to the other machines while overwriting the older folder. Again when I backed it up to auxiliary hard drives the backup was instant. When backing up to the two other machines (one with sdav on it) the other without sdav (but with other anti-malware) it was palpably slow. The progress bar could be seen moving forward then backward a bit with the process to move the 12 meg taking over a minute on a homenetwork with ethernet.

Initially I thought it was sd scanning incoming files, but the same problem is occuring when writing to a non sd machine.

And, the slowdown, this marked slowdown, is new since sd 7 just I hadn't been backing up directories until the last fews days just individual files.

I shut off intelliguard and the cross network backup was way faster (subjectively seemed slower than it was with sd6 but faster) and i don't have the time to shut off one intelli guard feature after another to check it out further.

If this slowness continues it will make full network backups almost impossible with sdav

[AChen]

From our testing on 2 PC's we set up network shares, both with SDAV installed, and transferred some 50MB files. We didn't experience any slow downs with SDAV running, all Intelli-Guards were enabled.

Could you try the following: In Settings–> Scan Settings-> try backing up with ‘Scan Archives’ temporarily set to ‘None’. See if this makes a difference?

Could you then try disabling File Guard to see if this makes a difference?

Thanks for looking at the problem and sorry you couldn't duplicate it.
I'm running everything on vista business machines, only protection is sd av

Initially archives were not being scanned anyway so did not run those tests.

Backing up the 214 item folder with pdf files to auxiliary hard drive took 8 seconds

Backing it up between two sdav machines took between 2 minutes and 45 seconds to 3 minutes each time

shut off the file guard and I thought it went faster but on testing two more times it took the same 2:45 to 3 minutes

When I shut off all of intelliguard (causing windows to panic) the backup between my two sdav machines took 28 seconds much better by doctor is off

I tried a similar experiment with a smaller 13 meg file mostly with wordprocessing files and got similar results

Turned back on sdav

Then and here is the interesting result: turned on my wife's machine that is guarded with other anti-malware stuff and backed up the same 214 item 42 meg folder from her machine to mine and that took 18 seconds

(back up time to the auxiliary hard drive on my desktop is about 8 seconds)

Anyway, it appears that something in SD is slowing down stuff as it leaves my machine.

I did a write over install not a clean install initially. If I should uninstall sdav and then reinstall it will it remember my account number. I once had real trouble with that.

Anyway, summary

vista business on all machines, sdav my two machines,
backup to auxiliary hard drive 8 seconds
backup between two sdav machines with file guard on and with file guard off between 2:45 and 3:00 on different trials
backup with all of intelliguard off was 28 seconds
backup from wife's business vista with avg full paid on it to my sdav machine was 18 seconds

(I started a similar comparison with a `12.5 folder with mainly text and word processing and was getting similar results)

Any suggestions ?Suggestions:

Very frustrated as wife and I co-author and really back up everything between machines

[tigertheboo]

any further suggestions of what to test?

problem persists. with the small files mildly annoying but when I do full backups the problem will be disabling.

[tigertheboo]

Dumb workaround idea, just checking. First I'm waiting until next build is put out for SDAV and then will uninstall and reinstall to see if that fixes the slowness problem.

But now the dumb question: large backups across the network work fine if sdav is shut off. I only do these backups intermittenly to do full 5 gig folder refreshes (I back up changes daily but these usually are small folders and the delays are mild albeit annoying).

If i were to unplugl my dsl cord (i.e. killing my internet, e-mail connections) I know my router still connects my three machines. Then I could shut off sdav and do the refreshes fairly quickly (about half an hour).

If i were to unplug the dsl cord and then shut off sdav am I adding any security danger to my computer. I'll restart sdav when I hook up my dsl.

Yes, it will remember your name and license code.

[haapy]

If the dsl modem is either off or unplugged, no internet access, therefore no danger.

If you use dial up modem connections you might want to unplug them as well.

As long as your pcs on your network are free of malware, no danger.

[tigertheboo]

Thanks
I was pretty sure it was safe but I'm a nervous type, having spent two days fighting some real mess on my wife's machine once and gave up on my own and re-installed os once. And, I'm cautious, don't surf silly things etc.

This is getting weirder.

Am testing out cross network back up speeds with the same folder with several hundred pdf files in which I first noticed the speed problem. The folder is slightly different as it is an active folder in which individual files are moved between subfolders but it is the same 41 meg with 200 plus pdf files..

Backed up stuff from sdav protected desktop to sdav protected laptop and to avg protected desktop.

Back up time to attached auxiliary hard drive was 8 seconds

All results duplicated no matter whether backing up to laptop or to other desktop and also duplicated when i shut off sdav on laptop.

With all intelliguards on backup took between 50 seconds and a minute.
When i shut off intelliguards one by one, backup time stayed roughly the same (a few second difference but most likely me and stop watch). However, therer seemed to be a speed up with browser guard was off and then perhaps when site guard was off.

I then tried to backup with both site guard and browser guard off at the same time and the backup time dropped to about 35-38 seconds. Really puzzling to me.

SDav was clearly alive in the background as it told me it couldn't access smart update files (I had unplugged my dsl that's why).

Anyway, stopping these two guards simultaneously sped up the backup


And, now the mystery deepens. Remember this is the same folder I had used before (though it is now located on my desktop rather than 2 levels lower in my documents). When I first noticed the problem it took almost 3 minutes to backup from users/me/mydocs/mymainfolder/projectfolder/backup folder and now from users/me/desktop/backup folder it takes a minute even with sdav on

Sorry for the length.

all machines vista business totally patched, two with only sdav and one with only avg (can't persuade wife to change yet)

[tigertheboo]

Well support suggested that i simply do a real clean install in safe mode.

Did so on one of the computers and tried to see if network speed increased.

Didn't appear to do so in backing up to a non sd av machine. .

Have no idea what to do next, other than leave the networked machines on over night when doing backups or shut off sd av and unplug the dsl cable.

Really puzzling.

Sorry to keep bothering you but the comparison was between version 6 and 7 and then between 7 and 7 being shut off and then between sending from a machine with sdav to one with avg and from the avg machine to the sdav machine. (both vista business) in all cases the network transmission speed of sd 7 was dramatically slower than 6, then with sd off and then from the avg machine to the sd machine.

Weird stuff. Hopefully it will go away in another build.

Do you have hard disk indexing on? If so shut it off. A resource hog with little side benefit.
Open Windows Explorer, right click the C: and click properties, uncheck allow indexing service. Do this for any other hard drive as well.

Same for Windows Search 4.0. Remove via add/remove programs.

The two items may help a tad.

What is the Kernel Compatibility mode set to? could you try changing this and rebooting to see whether this makes a difference. Remember, only change this according to your setup.

[tigertheboo]

Sorry for delay. Had to wait until i was home and wife was out so i could take over her machine for the testing. Created a 20 meg file with pdf so won't have to spend all day testing

Two points: one on current problem and then a point of interest

Current problem: my normal configuration is kernel compatibility mode on:

with kernel compatibility on and sdav off backup from wife machine to desktop was 16 sec, to laptop 20 (and from desktop to attached auxiliary drive 4)

with sdav on and kernel compatibility on backup times from my desktop to laptop and then to wife's machine was about 50 second

with sdav on and kernel compatibility off backup time from my desktop to the laptop and to my wife's machine dropped to 39 and 36 seconds, some increase in speed

Interestingly, the backup with kernel compatibility off into my machine from my wife's machine actually increased in time from 13 seconds to 27

None of the above makes any sense I'm puzzled.


An aside that developers might find of interest. With sdav 6 the network connection to laptop took forever (over a minute to open). When Haapy advised me to turn on kernel compatibility mode, the network connection opened more or less instantly. With sd 7 the network connection works fine no matter whether kernel comp is on or off .

Weird stuff and still puzzled but i can probably live with it

I'm not sure if I have totally powered down and repowered my dsl connections since upgrading. Will try that later but have to go back to my real work.

thanks for continuing to look

[haapy]

Try the new version. See if that helps.

Haapy once again your advice worked.

I did an override update to 5.13 just the straight forward plain vanilla upgrade and (knock on wood) the back up speeds have returned to normal.

thanks and hopefully doing so hasn't added some other new 'feature'

Interesting, i take a few days to work up courage to update. i had downloaded the original posting of 5.13 and had forgotten I had done so so downloaded it again today. Turns out the two downloads are a few bytes difference in size.

Both from pct site of course

Anyway, thanks people for the help and the time
