    I use an external USB 2.0 harddrive and backup all on partitions c and d. I do a full once a month and differential every three days.

    I can almost understand the full backup and verify, but a differential writes the file in 15 or 20 minutes then takes more than 12 hours to verify. This is unbearable.

    I have compression and priority set to normal.

    Is there something I am missing? The same type of backups when I was backing up to tape with another backup product never took more than 2 hours and usually less.

    What can I try?

    Thanks.

    What size is the TIB file for the full backup?
    What size (approximately) are the differential backups?

    How long does a full backup take?
    How long does a verify of the full backup take?

    When TI verifies a differential image I think it also verifies the full image it's based on.

    If you give some sizes and times then maybe something can be figured out.

    Also, what build of TI 10 are you using? 4940 is the latest.

    Thanks for the reply.

    Using 4940

    Full is 29 GB

    Differential is 500KB

    Full takes maybe 18 hours? I need to check that one again.

    Differential takes 12 minutes to backup, then I stopped the verfify at 38% after 10 hours.

    Are you doing the backup & verify procedures from Windows or the Acronis rescue cd?

    If you're using the rescue cd, it sounds like you don't have USB 2 ports or the linux drivers are not supporting them correctly.

    You say you have a USB 2.0 external drive. Do you know for sure that your computer supports USB 2.0?

    Through Windows. Scheduled.

    Just bought a new internal USB 2.0 Card to be sure, but that is an interesting thought. I'll exchange it to be sure that is not the problem.

    Well, you were right. 2.0 is not working.

    Just posted this elsewhere but if anyone has advice it would be most appreciated:

    I have an older ASUS motherboard, Windows 2000 SP4. Just bought a PCI USB
    2.0 controller and nothing I can do will install the driver. Finds new
    hardware, finds the driver then shows an error message and goes into an
    infinite loop of found new hardware.

    Is it possible it is conflicting with the built in 1.1 USB on the motherboard?
    If so, can I just disable that in device manager? BIOS?

    Something else?

    This one is frustratng.

    Thanks.

    Can you post the brand and model # of the PCI USB 2 card you have?

    Also the ASUS motherboard model #? CPU? RAM?

    It seems to be a driver problem with Windows 2000. I doubt that disabling the USB 1 ports on the BIOS will solve the problem. They usually coexist peacefully.

    I REALLY appreciate you trying to help. My current thought is maybe there is an IRQ setting preventing this from working.

    The PCI USB 2.0 card is an ADSTech USBX-2000. CLaims to use Windows 2000 native driver and the driver they include is identical.

    M'board is an ASUS P2B with PII 350, 1 MB RAM.

    Also thinking of deleting all the USB devices in Device Manager and seeing if they reinstall right. Getting tired of rebooting :^)

    This is a link to the ADSTech download page. Have you tried these drivers?

    Deleting/removing the other USB entries in the Device Manager may help. They should all be redected upon a reboot. You could also boot into safe mode and back into normal mode. This sometimes will sort out drivers.

    Also, if you have several PCI slots available try it in each one and see what happens. If it's an IRQ problem, installing in a different slot may help as it will get assigned a different number.

    You have SP4 for Win2000 already so that shouldn't be a problem.

    You could also try disabling the motherboard USB ports in the BIOS and see if that frees up an IRQ or otherwise lets the PCI USB 2.0 card work. I know I said that I doubted that would make a difference, but if the computer is low on resources, it may help.

    Post back and let me know if you got it working.

    Thanks again.

    Their drivers are plder than the Win 2000 SP4 drivers. So I don;t think that would be worth the try.

    I'm reasonably convinced it is not BIOS. Not the lack of IRQ unless its steering shared, but all is set to PnP so should not be a problem.

    Not sure exactly what I will delete and have Win rebuild, but at least the enchanced controller and anything that seems related./ But a bit bleary eyed after a day of tracking this one down. Or at least trying to.

    May not get to experiment further with this until tomorrow night. Will definitely post when I know more. ANd I do appreciate all your suggestions and hanging in there with me.

    Got it. Many hours. Many!

    Seems that some update must have removed a registry key - local machine /
    software / microsoft / windows / current version / runonce.

    Recreated the key and it installed instantly. Go figure. Was even tough to
    find Googling.

    Now off to see if USB 2.0 is really 40 times faster :^)

    Thanks again, Mudcrab.

    you ought to run at roughly 1gb per minute going from hdd to hdd. USB will be slower than that but nothing like 18 hours for 29gb -- more like an hour give or take.

    Did a trial Differential last night. Almost 3 GB. Took 1:22 to backup and verify.

    Tonight I will try a full backup.

    Maybe not "quite" as fast as I would have liked, but much, much better.

    3GB took over an hour to backup? It should have taken only a handful of minutes. It sounds like you're still transferring at USB 1.1 speeds. Is you're BIOS set to support legacy USB? You might ry changing that setting.

    That was with verifying.

    Last night was a full backup. 30GB give or take in 3 hours with verify.

    I can live with that. Much faster than tape backup speeds with verifying.
