Why, while backing up big files, does the program takes so long to compress?

Data Backup Software for Windows Professional Tool GRBackPro...
When you handle big files (normally over 100MB), the best strategy to use is to disable the compression. Normally big files are already compressed (say for example video files) and thus spending time to compress them further will give you no saving on space and loses time. You can disable the compression on a single Job by checking the Disable Compression (force copy only) option in your Job from the Add Job dialog box.

How can I compress my files for storage?

UIUC Math Department - Computer Frequently Asked Questions
You can keep files around in a smaller size by compressing individual files using the gzip command. You can use the tar command to package up an entire directory into a single file, which can then be compressed. To compress a single file, say thesis.ps, you can use the gzip command, like this: gzip thesis.ps This turns thesis.ps into thesis.ps.gz, which is typically much smaller. To reverse the process and get thesis.ps back, use the gunzip command, like this: gunzip thesis.ps.

What kind of files will compress well and which ones won't?

In general text files compress best since they repeat the same information over and over allowing the compression algorithm the greatest gains. Fortunately HTML and associated web site files fall into this category, so in general there are good gains to be had. Image files with JPG, GIF, PNG, etc. extensions are already compressed so there is no gain in compressing them again. Also MP3 audio and MPEG video files will not compress well for the same reason.
