NSDL has established extensive back up systems for computer and communication infrastructure.
NSDL uses hardware, software and communication systems, which conform to industry standards. Further, the systems are accepted by NSDL only after a rigorous testing procedure. NSDL's central system comprises an IBM mainframe system with a back-up facility and a remote disaster back-up site.
The NSDL hardware, software and communication systems are continuously reviewed in order to make them more secure. These reviews are a part of an ongoing exercise wherein security considerations are given as much importance as operational efficiency.
In addition to the enhancement of the services offered through the depository, NSDL is also working towards strengthening the systems and procedures to comply with the stringent international standards, that would further the confidence of the users of the system.
