academic service continue without
Disruption
Or
If there is a disurption, it is restored as

Data backups
1. How effectively can we perform, if our e-mails, correspondences, documents, reports and databases got wiped out?
2. How long will it take for us to build it from scratch?
3. Can you muster the energy and enthusiasm to recreate?
NACLIN2007NACLIN2007 99
With reference to Library what to backup ?
1. Bibliographical data or metadata
2. Full text contents of digital libraries - like faculty
publications, syllabus and question papers, project reports
3. Official correspondences, letters, internal communications
and reports
4. E-mails sent and received
5. Students and faculty downloads if done in library systems
in their designated folders
NACLIN2007NACLIN2007 1010
Educate Library staff regarding
1. Security awareness
2. Are we providing data security to our users
3. Importance of User ID and Password
4. Validity issues-Making old/lost Borrower’s card
invalid
5. Access Security to all systems
NACLIN2007NACLIN2007 1111
Factors to be kept in mind
1. Data backup and restoration
• At what periodicity – hourly, daily, weekly
In our .….
2. Imagine the hard work of years being lost just because
a file is deleted unknowingly by some staff
• Critical data – Circulation information
NACLIN2007NACLIN2007 1212
Operating System
• Update with required supporting patches and softwares?
• All required software downloads which was being used
during process of evaluation of the application program
till date
NACLIN2007NACLIN2007 1313
Take care of
• Physical security
• Hardware and other equipments secure ?
• Virus protection
• Updated and virus software available and being used
periodically are legal
• Account and password
• Only authenticated personnel to have access

Future plans
1) Outsource to vendors for online backups in a different
location may be daily or periodically depending on the
cost
2) UniVault XL 1000 series
Univault XL 1000 – Standard : upto 925 GB storage

Future plans
UniVault XL 1000 series- Store all critical and non critical information in one location- Securely share information with any computer
in the network- Lock access to data and reduce chances of information theft
- Rid the burden of taking frequent backups to
save information from computer failures
- Instant recovery of infected data files
NACLIN2007NACLIN2007 2323
Why Univault?
•Cost effective
•Online information content not critical-
unlike bank transactions
•Users can wait for an hour or two till the OS
and application software is loaded
•Data corruption reduced
•Secure OS
