18. with MegaRAID Recovery IT organizations can greatly enhance their level of business continuity data protection and restore capabilities How MegaRAID Recovery works MegaRAID Recovery preserves the state of information stored on a virtual drive at a specific point in time using a copy on write methodology This means that when data is written to a designated volume or virtual drive VD the original data that was present before being written over is then copied to a snapshot repository The VD will continue to accept new data while copying original data to the repository The snapshot repository will then continue to collect the original data that is being written over until a snapshot event takes place Once a snapshot is taken all of the new and old data on the VD becomes original data So the repository never becomes a complete copy of the source VD Figure 4 shows a server with three VDs and a single snapshot repository snapshot repository Applications and data Figure 4 Server with three VDs and a single snapshot repository As snapshots are taken and the repository fills with different Pils MegaRAID Recovery is able to restore a VD s data should volume or file level corruption or deletion occur Recovery offers two methods for restoring data e Restore from View Allows users to conveniently mount a view of the snapshot in MSM and drag and drop lost data and files back into the source data volume e Rollback Allows users to
