Compression default of v5? - lavande - 01-21-2025

Hello,

What is the default compression level since version 5?

When the stable version v5 was released, I uninstalled (and deleted the hasleo folder in program files) v4 to have the default compression level of v5. I saw that it should be low by default. I have medium by default with v5.

I made backups with medium level on several computers including old ones, it's okay for the processor and the time to complete the task.

The default compression level used by HBS V5 is low, if you have installed an earlier version of HBS, then V5 will use the compression level set by the earlier version. The default compression level is stored in the following registry value:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Hasleo\Backup Suite\TaskDefaultCompressionLevel

Thanks, I'll monitor CPU usage and time, and adjust compression if needed. And if I'm not mistaken I have to make a new task after changing the compression level, and delete the old ones.
TaskDefaultCompressionLevel=value 2, so medium.

Yes, the default compression level only affects newly created backup tasks, and Hasleo Backup Suite does not support changing the compression level of existing backup tasks.

I'm not sure too.

When I create a new task under v5.0.2.2, it always DEFAULTs to LOW compression... this used to be MEDIUM under previous versions.

On a fresh v5 install, the above mentioned REGISTRY Key doesn't exist so the app DEFAULTs to LOW compression.  When that key is added manually with one of the following values, it becomes the new DEFAULT compression.

0=NONE
1=LOW
2-MEDIUM
3-HIGH

I hope next version allows us to change in the backup settings

We will implement this feature as soon as possible, but there is no guarantee that it will be available in the next release.

If an image backup at low compression results in a 100 GB file, what would the approximate file size be at medium and high compressions? 

Trying to determine if going to medium or high compression is worth the time or risk.

Thanks for any insight on this.

A tried and tested lossless method is used for all the DATA compression options... no risk is involved.

I would suggest testing it yourself to get the answers you require.  A warning... if using a modern CPU (4-cores or better) and having fast SSDs (NvME or SATA III) involved as a SOURCE and TARGET disk in the compression tests, you will most likely saturate your CPU capability as you raise your testing compression level.  If using an HDD in either position will easily throttle the CPU usage and not saturate your System.

Best to give it a try yourself...
