I’ve recently updated 2 Domino servers from version 7.0.3 to version 8.0.1. Both server are hosting 600 mail files. The filesize varies from 30MB up to 10GB. Hence one of the server nearly went out of available disk space, I enabled database design and document data compression, which is a new feature in Domino 8.0.1.
To use this feature, the NSF must be ODS 48. To upgrade the database to ODS 48, enter the following setting in your NOTES.INI file:
Create_R8_Databases=1
For the Notes client mail template (MAIL8.NTF), this setting is enabled by default and the design is compressed when the mail database is created. For all other databases or if you update from a previous Domino version and keep the design of your mail files, you must manually enable the setting and then run a copy style compact on the database.
It took about 48 hours to compress all mail files. The results of the compression are listed in the picture below:
170GB freed space is a good result. This is 170GB less data to backup. What is your experience with the new Domino database design and document data compression?
Hi
I’ve done a little test myself with mixed results. See here:

http://www.d2k.nl/domino/blog4.php/2008/03/05/notes-8-design-and-data-compression-part-2
I had one Notes database (Lotus Knowledge Base), where the note compression freed 46 percent – not bad.
I also saw close to 50% on one but it was cheating. The database was the Lotus KBase which is almost entirely non-summary data. Otherwise the results that I’ve been seeing are similar to the numbers above.
I’m a nit wit, I didn’t read Andy’s whole post that he did the KBase also 😉
Did you perform a compaction of all of these Dbs before to upgrade to ODS48?
If you did not, you mixed the results of the ODS48 migration with the results of a standard compaction…
Alan.
@Alan: Yes, I did a compact the day before the update to ODS48. I had the same things in mind regarding mixing up the results like you 🙂
@Alan: so did I before copying the files to the testserver.
