A search on the lotus notes iDataAgent Catalog retrieves a database’s transaction log and associates it to a specific Notes Database. The transaction log is broken into scaled-down data files called sign extents. Each one is 64MB in size. Each sign extent has the date that shows the date when the database was created and also the date it was run by the Fixup activity.
There are several levels of raid. Each offers different performance and fault tolerance. RAID 1 is the most common, as it uses mirroring to basically double the storage capacity of a system. However, it’s not foolproof. If the failed disk is mirrored, it will take hours to recover data from the remaining drives. RAID 5 is a different option that combines striping with parity to offer good storage and performance. It requires two additional disks for parity, but it offers the best performance and storage.
