DC Protect

1. DC Protect Innovative backup and restore solution

2. Some questions to think about... • How many percent of the data on your servers gets backed up on a daily basis? • Is it easy to restore data in case of an emergency? • Do you check regulary that your backups are still functional? • How much time and resources does it take to perform and maintain your backups? • Is it an automated process or does it require frequent manual interventions? • How much does it take to troubleshoot backup errors? • How easy is restoring your data ? • Is the restore process going smooth ?

3. Key aspects to address • Backups must be reliable • Tape backups sometimes fail: • Order of tapes gets mangled up • Tapes have a limited lifetime (tape strech, alignment) • An incremental backup plan increases speed, but significantly decreases reliability as well • Diskcopy operations tend to fail on open files • Backup & restore operations must be as fast as possible to minimize downtime • Tape restore operations are much slower and requires ‘tape juggling’ • Distributed backups have to use minimal network bandwidth and storage • Only data that is not stored already should be backed up at a central location

4. Key aspects to address (cont.) • Backup & restore operations should be easy to perform • Central management and event monitoring • Backup solutions must be easy to setup and be scalable as well • Support for all major operating systems (Windows, Linux, Solaris, HP UX, IBM AIX..)

5. DC-Protect overview • Product positioning • Disk Based backup • Content-Based file backup • Distributed SW Client – HW Server based • Features • Full daily backup with long retention rates • Instant restores • Self service web interface • Value offering • Protection of information, reducing business risk • Rapid Return on Investment, lower requirements • Installation in minutes not weeks • Scalability first, supporting any size server farm,from 10 to 1,000s of servers • HW/SW independent, supports various OS and server types • Product concept & design • Prebundled Software/HW • Installed on redundant DC-Protect Storage Server • per 50 servers one DC-Protect Storage Server • Works with any NAS/SAN

6. Feature Overview DC-Protect

7. DC-Protect Features • Disk based backup • Content based backup • Efficient data storage • Minimal network throughput • Self-service Backup & Restore • System rollback / roll forward • Central administration • Off Site Backup

8. Disk Based Backup • Fast backup data transfer • Only unique files are transferred • Transfer speed determined by network and disk speeds • Immediate and fast file restore • Files are online • no slow searching through tapes • Files are stored in full version • no incremental backup reassembly

9. Efficient storage/network throughput • Existing backup methods copy all data from the servers to a central storage medium. Storage and network capacity needed to execute this process is overwelming. • Our patented content based backup scheme will reduce those requirements upto 1/1000 for needed network throughput and upto 1/100 for needed storage.

14. Parallel backup operation • Agents on the target machines perform backup tasks in parallel and simultaneously. • This allows to backup a large number of machines within a tight backup window • This guarantees datacenter grade scalability of the backup solution.

15. Agent • Light agent • 2 Mb RAM usage • Minimal bandwidth usage • All files are compressed before transport • Self contained: • Does not install anything outside its own directory • Does not rely on any functionality of the OS to operate

16. Agent • Server agents • MS Win 2000 Server / Adv. Server / Datacenter • MS Win NT4 Server • Linux • Sun Solaris • BSD (Planned) • Client agents • MS Win 98 SE (Planned) • MS Win ME (Planned) • MS Win NT4 Workstation • MS Win 2000 Home / Pro • MS Win XP Home / Pro • Linux

17. Self-service Backup & Restore • Our intuitive self-service interface lets customers/divisions managers and end-users schedule and restore their own backups. • The DC-protect backup server has supervisory control over the backup cycle and will guarantee a working backup. • To recover lost data, the user can simply log on to a web interface and restore the particular version of the file or even full system.

20. Backup Schedule

21. System roll back / roll forward • Each day a restore set is made of the system. • A resore set is a text file with all the information about a (full)backup run. This file is the only thing needed to restore a server to its original state. • Because of DC-protects unique technology we maintain all data up to 3 months on a day to day bases. • DC-Protect can restore full or partially a server upto 3 months back and roll back or forward. E.g. You can decide to roll the server back to a date 6 weeks ago, you can change your mind and roll the server forward to a date only 4 weeks ago.

23. Central administration • The administrator is able to install, configure, and administer the “client software” from a central location. • The administrator is able to install, configure, and administer the “storage repository” from a central location. • Web Interface to DC-Protect server and agents on target machines

24. Central administration interface

25. Security • Public – Private Key mechanism for Agent Authentication • Encrypted SSH tunnel for Agent to server communication encryption • Pass phrase encryption of user data • Data is encrypted before network transfer • Data remains encrypted while stored

26. Redundancy • DC-Protect server redundancy • Storage redundancy M S M S

27. Open and firewall friendly • DC-Protect is based on an innovating, highly scalable multitier architecture using open standards: • HTTP protocol • FTP

28. Easy to install and use • Preinstalled on a base unit: • Initial configuration through LCD • Web based central graphical user interface

29. Platform • HW platform (1U) • Basic Configuration through front LCD display • Terminal connection for disaster recovery • Minimal (no) maintenance design • Internal HD for logging information. • 6 network connections (4 * for connecting the storage (e.g. DC-Storage or 3e party NAS, 1 * for connectivity towards the servers link, 1 * for redundancy sync and heartbeat) • Optional redundant configuration • One DC-Protect platform for up to50 servers to be managed. • Runs our DC-Protect orDC-Operate software.
