Each vault store database has an initial storage requirement of 100 MB for the data device and 80 MB for the transaction log device, making a total initial disk space requirement of 180 MB for each vault store database.

Ensure that there is adequate space for database devices to grow as data is added. Transaction logs should be limited to an appropriate size for your back-up and maintenance plan.

A basic sizing guide for each vault store database is 250 bytes for each item archived plus 5 GB for static data, transaction logs and temporary data fluctuations.

If you configure a vault store partition on an EMC Centera device, and the partition is enabled for collection, then an additional SQL index may be created for the Saveset table in the associated vault store database. The space required for this index on the SQL Server hosting the relevant vault store database is approximately 27 bytes per row in the Saveset table. For more information on this index see the document, http://entsupport.symantec.com/docs/288036, on the Symantec Enterprise Support site.
