Extending Browse time would need more disk space under /nsr/index -
this all depends on how many files get backed up too - but if your
system has been running for 1 year, and your browse time is 1 year then
/nsr/index should be roughly as big as it will get - you can multiply
the space by 5 to get an estimate for 5 years (an overestimate perhaps,
but you need to allow for increasing demand anyway).
Most people chose a browse time of about 1 year, even if the retention
period is 7 or 10 years.... All it means is that you may need to do an
index recover every now and then if there is a need to browse back past
a year on a particular server (that's what the nsrck -L7 command is
all about).
Extending the retention period means that the media database under
/nsr/mm will get larger - but it is not much to worry about
usually.... Eg on a site I run we have (on average) 9 months browse
time, and many more years retention... The indexes add up to about
400GB, the media DB is only about 500MB.

Would extending the browse and retention policies that much require a
lot more disk space on the Networker server for the indexes? Which one
of those policies if extended would need more disk space allocated for
indexes,etc?
