Backup File Compression
Posted by: Gregory Gebert (ID *****6050) Date: June 18, 2002 at 16:04:10

Several weeks ago, I performed all the project utilities on my main project and library files, pack, reindex, check, as well as the Windows maintenance routines, defrag and scandisk, not to mention running the latest version of Norton VirusScan. Of course I backed up the last version of my data. I keep each backup filed by date, and only get rid of earlier versions when my 100 Meg Zipdisk can't hold them.
I have done this operation before, and I noticed that the new version of my data was slimmed down, but this time, the data and library files for my 6500 individual project file dropped from 20+ meg to 14+ meg, and when sqz'd, it was 9.5 down to 5.5.
This huge drop in the compressed file size made me think I had lost something through all my massaging, but the project info window says I have all my individuals and the total file size is still 20+ meg, although when I back it up, the little screen says the file size is 14+ meg and will take some time to transfer.
I have been working with old and recent data, and I can't find anything that indicates lost data, yet.
Can I place absolute faith in what the project info window tells me about my project, or should I look for something gone awry? Is there any need to analyze the condition of my files further, and if so, how do I do it?
Sorry to be such a worry wart, but I have 13 years and tens of thousands of dollars into my files, and I don't need the anxiety that goes with lost data. If I learn that the utility operation somehow corrupted my files, and I should restore my earlier files, I will have lost just a few weeks of data entry, but that would be better than to find out belatedly that huge chunks, or whatever, didn't survive the journey.
Thanks, Greg Gebert
