Compression default of v5?

[admin]

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.
