TeraByte Unlimited

I have Image for Windows 2.65a. To image 750GB worth of HD movies on a 1TB drive using standard compression takes 30 hours.
- computer is not multi-tasking and is dedicated solely to backing up
- issue is not phylock. Phylock gets a lock right away.
- speed is not throttled. I have a quad core 3GHZ processor and all four cores are operating at about 75% of capacity in task manager
- the target and backup drives are same make/model: 1TB Western Digital 7200rpm. Operating system drive is a 300GB Velociraptor 10,000rpm
- all the settings in IFW, as far as I remember, are standard. I did'n't do any tweaking that I can recall.
- "Validate", "Validate Byte-for-Byte" and "Encrypt" option boxes are left unchecked.
- "Omit page file data" and "Omit hibernation data" options boxes are checked.
- Compression is "Standard"

This length of time does not seem right. Acronis takes perhaps 5 or 6 hours to backup. 30 hours seems way way too long.

Any ideas?

jaydub,

That is an old IFW version. I suggest you use ver 2.75. You could try Enhanced Speed - A compression but your movies won't compress much.

Use the information button to check each partition to ensure you see
free/used space. Check your drives with a good benchmark utility
(sometimes updating/reinstalling the driver fixes issues on drive speed).
Uninstall anything that could be in the path to the drives slowing it down
as well.

Presuming it's an internal drive on both sides and using the windows file
path (not direct), probably take about 5 to 6 hours standard, enhanced speed
a, much less than that.

Per HDTune,
O/S drive has 94MB/s throughput (average across the disk) and average access time of 7.1 ms
Target drive has 86 MB/s throughput and average access time of 14.4 ms
Backup drive has 62 MB/s throughput and average access time of 15.4 ms
All drives are internal. Checked the healthiness of the drives via SMART and Speedfan, and no obvious problems.

You say "Uninstall anything that could be in the path to the drives slowing it down as well". Can you clarify?

You also say, "Presuming it's an internal drive on both sides and using the windows file
path (not direct)...." I am backing up via WinXP SP3 O/S partition on HDD0, with the target being an HTPS partition on HDD1 to a backup HTPS partition on HDD2. All windows, all internal.

I'm still stumped. Perhaps choosing "No Compression" would help as video doesn't really compress much any way. Can't believe though that that alone would reduce backup time from 30 hours to 6.

standard compression doesn't handle uncompressible data efficiently, so
could be part of it, but enhanced speed A does, but no point, if you have
mainly compressed data, just don't enable compression.

Something else to check is to ensure that there is no other
disk-intensive activity occurring during the imaging process. e.g.
anti-virus scan, defrag, file copy, etc.
