Full Backup takes too long

Thread needs solution

I am running Version 9.1 for server (SBS 2003)and have been doing a full backup to an external hard drive and everything was OK. I have replaced 2 of the external hard drives with an Iomega 500GB (powered by USB) external drive. My first full backup is going to take 2 days. Any ideas or suggestions?

Thanks

Hello Alan Shody,

Thank you very much for posting. I will definitely help you with this issue.

If I understood correctly, this problem began when you switched to the Iomega external hard drive. If you try transferring a considerably sized file to this external hard drive through Windows, does it take less time? Have you tried plugging in the external drive into the back panel of your server?

Please try enabling caching for the USB device:

Right-click the "My Computer" icon and then click "Manage";
Click the "Device Manager" icon;
Click the plus (+) sign next to "Disk Drives";
Double-click the "USB hard drive" string;
Click the "Policies" button then click "Optimize for performance" and mark all checkboxes.

Can you please let me know if you require additional assistance or have any other questions.

Thank you.

Thank you so much for your suggestions. I tried all of your ideas and have come to the conclusion this USB drive is very slow with file transfer. I have gone back to the external desktop drives (Vantec case and a Seagate 7200 RPM with cache and the backup completes in 3 hours.

Again thanks

Just purchased True Image and have beeen running entire PC backup to Acronis Cloud for 2 days with 52 gigs to go over an estimated additional 3 days 16 hours to go. Must be doing something wrong. What might it be?

Hi Eugene,

Backing up to Cloud utilizes your Internet Connection and the upload speed is critical for the backup time estimation.

If you have a 100MBit/s Internet Connection it will have in most cases ~5 to 10 MBit/s as upload speed. Let's see what you have..

80 hrs for 52 GB

52GB = 52*1024MB = 53248MB

80hrs = 80 * 60 * 60s = 288000 sec

53248 MB / 288000 sec = 0,185 MB/s thats ~1.5 MBit/s and should be your upload speed.

Can you confirm your Internet Connection Speed is 1.5 MBit/s for uploading data?

Ran several speed tests: Upload from 0.74 to 1.32 Mbit/s. I wonder what I'm paying for? Maybe I'lll stick to a local external disk.

Might be best.

But once you have uploaded the 52GB next backups can be incremental or differential. The data amount should be around few hundred MBs per day for normal usage.
