How to roughly estimate performance improvement by archiving?

Hi Alex,

Performance estimates are always a touchy subject and difficult to quantify especially in your case where you don't have sufficient data points. Also performance is very subjective and dependent on a number of external factors such as Servers, Network, Users and peak loads, etc.. Rather than to try to frame it to the business as a performance improvement, try to illustrate the benefits they can expect to see from such a undertaking. I am thinking primarily of cost factors such as: a) How much does it costs you for 1GB of Database space?, b) How long does it take to backup and how much does backup space cost, c) How long does it take to recover from a catastrophic failure e.g. DB restoration or complete System restoration, d) If your company has plans to go HANA, each GB of data will cost you an arm and a leg. These are factors you can estimate with the data you have at hand, everything else is a gamble.

PS. You might also find other, non-functional areas in SAP with extensive growth, these are typically the areas you go after first to trim down your system and gains are sometimes quite easy to realize with simple DB Reorg, etc.

Good Luck,
