2 2 Asynchronous IP Mirrors (AIM) Overview Asynchronously mirrors select application server data (volumes) to a remote disaster recovery site Windows, Linux, Unix and Netware volumes Utilizes TCP/IP protocols over standard IP transport mechanisms (Wan/Lan) to transfer data to the remote site Transfer speed is a function of the internet transport performance Easy configuration steps to set up source (local) and destination (remote) relationships Configured with a GUI at the source site Interfaces with Snapshot services at the remote site to allow independent access to the data Offline applications Backup Ensures Database Volumes Sets are in synch

3 3 AIM (Normal Operation) AIM Operations AIM continuously captures incoming write operations into the AIM source buffer For defined AIM source volumes only AIM source buffer files containing source volume writes are transferred to the destination site utilizing TCP/IP protocols over the Wan/Lan. Synch point markers can be inserted into the write stream at any time Or synch point markers can be inserted into the write stream in conjunction with a Database quiesce point The AIM destination buffer receives incoming buffer files Volume write data contained in the buffer files is written to the destination volumes in order Synch point markers are used to trigger destination volume point-in-time Snapshots For Backup For use by other applications

5 5 AIM (Initialization) How to Get started 1.) Temporarily Quiesce application server I/O (e.g., SQL, exchange) 2.) Take a point-in-time snapshot of all configured AIM source volumes 3.) Define source and destination volume relationships using the AIM GUI Disable AIM transfers over the internet (Wan/Lan) Blocks transfers to the destination site 4.) Re-start application server I/O 5.) Backup the point-in-time source volume data 6.) Transport backup tapes to the remote site 7.) Restore source volume backup tapes to initialize destination volumes 8.) Enable AIM transfers over the internet (Wan/Lan) The AIM buffer transfers writes in order to the destination site volumes
