What Should be the backup time of my 600VA APC UPS under normal load (movie, internet etc)
UPS Backup Time?

depends on your pc config.to get an idea do this:
1.go to extremevision online power calculator eXtreme Power Supply Calculator
2.calculate your pc load(select system load as per your situation when watching movies/browsing etc as default value is 90%).
3.calculate total load on ups by adding load of pc calculated in step 2 & of other devices connected to ups like monitor.
4.backup time=(58320/total load calculated in step 3) seconds.

about 6 min assuming 60% system load(minimum value in online calculator) which is high for normal usage.for general usage it should be ~30% or less so backup time should be ~12-15 min at least.
2-3min while gaming & 10+ under light load (movie, etc).
it giving me 6 min full backup during internet surfing (BSNL modem is also on UPS) and then beeping continuously for 2 min til shutdown. Is it ok?
8min backup? this is more or less ok.
@ OP - this should give you an clear idea - look at the Runtime Graph
