you can use simple math:
3 Mbps = 300 kBps
300 kBps * 3600 seconds (1 hour) = 1.08 GBph
1.08 GBph * 24 hours (1 day) = 25.92 GB per day
1000 GB (1TB) / 25.92 = 38.5802 days
This math does not take into account compression. Even at the best rate of
compression (let’s say 50%), you would need 19 days.
I would suggest you start thinking about two stage backup.
1st stage disk based.
2nd stage tape based.
With fast arrays/SANS and link speeds 2GBps and above.
You’ve got steps above, just substitute the numbers.
Good luck
