Challenges to Data Recoverability
Secondary copy of data needed to meet disaster-recovery requirements
– Current RPO with traditional tape backup has high risk of data loss
Restoring from tape can take weeks– Long outages mean lost productivity and revenue
Logical threats, such as operator error, accountfor 80% of outages
Users need continuous access to the data

What About Monitoring Application Faults?
In the event of a site disaster, AutoStart would relocate application resources from Site A to Site B:
– Ensure read-write access to remote replica– Start application resources– Start RepliStor replication from Site B to Site A
EMC AutoStart manages automated application and data restart on an alternate server, either local or remote
AutoStart seamlessly transfers control of application and storage resources to a local or remote facility in the event of an outage
AutoStart provides functionality to assist in automating failback of services, applications, and data
AutoStart manages RepliStor remote replication as a data source

Example: Inter-company Distribution Opportunity:
– Geo-imaging company distributes new images to its customers via CD
Problems:– High cost, manual intensive, slow, unreliable– Hard to verify delivery and trigger invoice
Solution:– Automate distribution to resellers and customers– Using certified delivery option to automatically
trigger invoicing
Benefits:– Significantly reduced distribution cost– Immediate delivery, availability to users– Improved TTR

OnCourse Unique Functionality Bandwidth throttling—Allows you to limit the transmission bandwidth so you use only a fixed number of bytes
per second in the transmission channel, optimizing the use of the network without causing a bottleneck
Incremental transfer—Users can choose to send only the changed bytes in a file to be transmitted, reducing network usage
Encryption—Users can choose difference encryption standards, up to 3DES encryption or external encryption (Verisign, DOD, etc.)
Synchronizing transfers—Users can make the directories on both sides exactly the same; files that are added at the source node are shipped over to the target node, while unchanged data is skipped; fields that are deleted in the source node will also be deleted in the target node
Certified delivery—Immutable receipt; the log file in the DTM host will contain proof of delivery
Notification—Users can enable e-mail notification of successful file transfers as well as failures; log files of the submitted jobs can be attached in the e-mail
Rollback—This function ensures that all the specified files arrive correctly in a group; otherwise, none of the files are applied
Move directories—This allows directories and their contents to be moved recursively so that the child directories and their contents are also copied
Core-to-edge, edge-to-core, peer-to-peer—The transfers can be in any direction, in both push and pull modes
Content distribution—Securely copies large files over the Internet
Content aggregation—Collects files from branch offices, back to the central office
Directory synchronization—Users can use the synchronization option to replicate one remote directory to a local directory, or vice versa
