How to Split NSF Database into Multiple Smaller Parts?

Posted by datarecoveryblogger
Have you ever stuck in a situation where you are having large-sized files? A computer file which has a bulky size may cause serious troubles for users. Just think you are a Lotus Notes administrator where you have an NSF database which is fairly large in size. Do you have any idea how annoying it could be for you if you are having a large-sized NSF database? Being a database administrator, you have to deal with such large databases. One day you find that the database has become too large to handle comfortably. You will start noticing an abnormal behaviour in your Lotus Notes client, such as: slow performance, frequent crashes, hangs while opening database, and many more. And the worst thing is database corruption which may occur due to its large size. 

Now the question which is asked fairly often is how to handle a large-sized NSF database. Splitting the NSF database into multiple smaller parts is the only thing users should be looking for. Many times it is seen that users ask if there’s a method for splitting the contents of a large NSF database into multiple smaller parts. 

There are two ways by which you can split NSF database into two or multiple parts. You can either try the Archive Mailbox Reverter (AMR) which enables you to specify date ranges to split the NSF database file. 

Archive Mailbox Reverter (AMR) is a mailbox archive tool which allows non-technical users and Domino administrators to revert archives. The archived mail items are moved back to the user's server or local mailbox. Domino administrators can revert archives for single and multiple users. 

Though the primary function of Archive Mailbox Reverter (AMR) is to revert mailbox back to a primary server or local mail replica, but it can also be used for splitting NSF database file. Follow the simple steps given below to know how to split a large NSF database file into two parts: 

Step 1: Create a new local mailbox (archive 2) using a mail template.

For that, click File > Application > New > Mail (R8.5) Template, and enter a title and filename FileName.nsf, then click OK

Note: In order to disable encryption, you can click the Encryption button before clicking OK

Step 2: Open the new local mailbox (archive 2), then configure the archive profile to point to the original archive (archive 1). i.e. archive\FileName.nsf

Step 3: Edit your IBM Notes location and change the mail location to local, i.e. Mail file location: Local. 

Step 4: Edit your IBM Notes location and change the mail file to the new local mailbox filename (archive 2), i.e. Mail file: archive\FileName2010.nsf. 

Step 5: Now launch AMR tool and generate archive report using AMR Lite mode

Step 6: Edit the report document (profile) displayed and add the original archive mailbox (archive 1) filename to the "Archive Files(s)" field. i.e. archive\FileName.nsf. 

Note: This step is not required if you copy/paste 1 email message to the new local mailbox (archive 2) and test archiving it. i.e. archive\FileName2010.nsf

Step 7: Click Revert archives and specify a date range, i.e. Jan 1, 2015 - Jan 1, 2016.

Important note: Once you are done this, don't forget to change your IBM Notes Location back to the original primary mailbox settings.
