A search in the lotus notes iDataAgent Catalog retrieves a database’s transaction log and associates it to a specific Notes Database. The transaction log is divided into scaled-down data files called sign extents, each one 64MB in size. Each sign extent has the date that shows when the database was created and when it was previous performed by the Fixup process.
There are several levels of raid. Each level offers different level of performance and the ability to handle faults. RAID 1 is most common because it utilizes mirroring to double the storage capacity. However, it’s not foolproof. It can take several hours for the remaining drives to restore the data if the mirror disk fails. RAID 5 is a different option that combines striping and parity to offer good storage and performance. It requires two additional disks for parity, however it is the most efficient combination of efficiency and storage.
