CPU usage nearly 100% as long as TI is running: Who also has this problem? Or is this normal?
- Acronis TrueImage Home 2009, last build
- Windows Vista 32 Bit, all current updates
- Intel T9500, 3 GB, 200 GB HDD with hardware-based FDE
- No applications running during backup
- Also no Antivir, no search indexer, no defrag nor any other background processes running
- CHKDSK done, no disk errors
- Distributed Link Service deactivated

TI is - in general - doing what it should: It backups at about 72 GB/hour (= around 20 MB/s maximum USB transfer rate) via USB 2.0 to an external hard drive, encrypted with AES 128 Bit (but it's the same without encryption, as I tried).
But CPU usage is nearly 100% as long as TI is running, that leads to:
1. Startup takes about 15 seconds.
2. Once I start the backup, TI as well as the whole PC nearly no more react. For example, when I click any button in TI during backup, it often does not react at all or sometimes take about 30-60 seconds.
3. The processing steps show up only partially and very slowly. Often, TI shows up "4 hours rest time", immediately before backup is finished then.
4. lsass.exe and TrueImage.exe both have very high CPU usage - TI.exe OK, but why lsass.exe?
This already was the same with TI on my former PC with Windows XP.
Is this normal, is it the same on your side?

In Task Manager does one of the servicehost entries also have a high CPU time?
Even though it may not be running, do you have PerfectDisk installed?

Dear Colin,
no, I have no "PerfectDisk" installed.
What do you mean with "servicehost entries" in task manager? As mentioned above, when TI is running, only TI.exe and lsass.exe have high CPU load, only these two (and lsass.exe even more than TI.exe).

Now, after several unfortunately all useless contacts to Acronis, I solved the problem myself.
Go to folder:
C:\ProgramData\Acronis\TrueImageHome\Scripts
In this folder, you find one script per backup you already did since Acronis was installed. Create a new subfolder (for example "Archive" or "Old") und move the old scripts into it. As soon as you have done this, you will wonder how fast True Image's user interface can react again during work!

can someone explain why the solution by dark_rider cures the high cpu usage?
what's the logic behing those "scripts"?
