In general, staff have no concept of the fact that making their ‘own copy’ of files that are kept on shared drives is a total waste of space. It’s why they will quite happily send large attachments to a huge mailing list. Why they will happily keep hundreds of poorly focused photos they took on their personal ageing and decrepit camera (even though the department has a brand new one supplied by the school). And, like all the waste printing, it certainly never occurs to them that the money spent on additional storage is ultimately taking money away from a child’s education.
That’s why I love Single Instance Storage.
I ran an analysis on our main storage server today. There are a total of 193,306 duplicate files. By using SIS to eliminate the additional storage requirements of these duplicates, I have so far saved 87.5GB of space. This is approximately 7% of all the user data on that server.
If you’re not using SIS – think about it.
