6. 7/2/18MIT, PUNE6
No. Year Name of Paper Description Advantages Limitations
1. 2016 Backup and Disaster
Recovery System for
HDFS, IEEE
 Backup of file
system
 No version
dependency of
HDFS
 Full File System’s
backup is
possible
 High speed
transmission
needed
2. 2016 On the Advanced
Strategies of Next
Generation Online
Examination System
Implementing Cloud
Based Standardization,
IEEE
 OES using cloud
based services and
technologies.
 Backup and
Recovery of
application
 Huge numbers of
examinees can
appear.
 Need of
Internet
connection
3. 2014 A Cloud Environment
for Backup and Data
Storage, IEEE
 PVFS2 (Parallel
Virtual File System)
 PVFS2,
performance is
improved
 PVFS2
needed for
concurrency.
4. 2014 DR-Cloud: Multi-Cloud
Based Disaster
Recovery Service,
IEEE
 Multiple clouds
 Resources
limitation
 Replicas on
multiple cloud
 Increase in
cost

7. Gaps In Literature Survey
7/2/18MIT, PUNE7
• Approach looks expensive
• Security mechanism is not specified
• No error correction and detection mechanism
• No Packet delivery confirmation

8. Problem Statement
7/2/18MIT, PUNE8
To take backup and restore state of application on multiple
devices using cloud services and web services.

9. Justification Of Problem
Statement
7/2/18MIT, PUNE9
• Solutions to prevent loss of volatile data
• Save users significant amount of time
• Avoids rework
• Lowest backup cost

10. Techniques Used
7/2/18MIT, PUNE10
• SELENIUM webdriver tool
• CRIU

11. 7/2/18MIT, PUNE11
• open source tool for assisting with the
development of test automation.
• supporting test automation.
• key feature is the support for executing
one’s tests on multiple browser platforms.
Selenium webdriver tool :

12. 7/2/18MIT, PUNE12
CRIU
• Used to implement checkpoint/restore
functionality
• Applications:
1. Live Migration
2. Snapshots of Apps
3. Process Duplication

13. System Architecture Diagram

14. 7/2/18MIT, PUNE14
Overall system architecture

15. 7/2/18MIT, PUNE15
System Flow

16. 7/2/18MIT, PUNE16

17. 7/2/18MIT, PUNE17
Algorithm For System Application
 Generate Dump Files of Applications.
 Upload it on Cloud.
 Download those Dump Files from Cloud to Restore
Applications.
 And then Restore it using CRIU.

18. 7/2/18MIT, PUNE18
Algorithm For Web Application
• To Restore session , Get cookies for Web
Applications.
• Upload Cookies on Cloud as Backup.
• Then Download Cookies from cloud.
• Add Cookies to Browser and Open Web App then
Web App session will be restored.
• To retrieve Web Forms, Get All Fields of Web Forms
and their values.
• Write them on JSON File and Upload it on Cloud.
• To restore Form, Read JSON File Contents and Set
attribute and Values.

19. Applications
7/2/18MIT, PUNE19
• Support real time applications
• Effective for large scale data processing.
• Support the applications from local failures (high
availability) as well as site failures (disaster
recovery).
• Recover across multiple devices.

20. Future Scope
7/2/18MIT, PUNE20
• Suggest the best method to go about securing data.
• Platform Independence.
• Generalizing the system.

21. Conclusion
7/2/18MIT, PUNE21
• System being used for application state restoration.
• Different techniques to backup and restore the data securely
and in optimal fashion.
• The system allows to restore the application state on multiple
devices.
