Write it on a Rock

I have a script that crawls the mail directory and logs the date, number of mailboxes and total space used along with writing out the user and size of their mail database on that particular date. I really don't know why I have (or want) this information but because I do have it I can tell you that on October 17, 2005, we had 461 email databases for a grand total of 69.54GB. Two year later that had grown to 532 email databases for a grand total of 219.9GB. A server program runs Mon-Fri that compacts our databases and reclaims the white space provided there's more then 10% but disk space was becoming an issue and I was very excited about the space savings potential in Domino 8.

To start taking advantage of the new compression available in Domino 8, I added the notes.ini line "Create_R8_Databases=1" to my servers on Thursday after I got LEI for iSeries downloaded and installed which brings my total to 6 out of 8 servers up and running on 8.0.1. This weekend I upgraded the mail databases by running the compact command with the -c option to bring them to the ODS48 format. Here's what our mail folder looked liked after the upgrade on Thursday and then this morning after the email databases were upgraded.




Amazing. That's about 28.3% savings with just the design compression enabled. I don't know how much I'd see with document data compression turned on as well but I'll keep you updated!
