backing up 2 tb of data

Can someone recommend the best solution to backup 2 tb of data and 60gb on a server on a different floor? I have Symantec Backup exec. I had a tape drive that just crashed so I have a couple external drives for now. I will need to copy the 60gb over the network.

So maybe a full backup on the 2tb and then do incrementals the whole week? Im worried about how much time it would take. These are production shares so hopefully they can be done over a weekend or overnight?

Backup Exec shouldn't have a problem copying 2tb over a decently fast network (1Gb+). We reguarly backup 10tb a night with this setup.

if the external drives are connected locally, then it shouldn't take that long for 2tb or even 60gb over the network.  start it early evening and should be fine

Backupexec is a good piece of software. We normally backup over 4TB of data over 1G network daily to NAS devices and it works like a charm. 60GB over a network should take no more than couple of hours to complete.
The best solution depends on your needs.  Do you need to take the backup offsite each night?  Are you looking for a cloud backup solution?  I would say replace the tape drive and be done with it.  The 60GB across the network shouldn't be a problem at all as long as the network is reasonably fast as stated above.

There are cloud backup solutions that are feasible, and we have one client that does a backup of 5 TB currently and it works great once the initial backup is completed.  I would evaluate the costs of different solutions over a couple years vs replacing the tape drive.  As much as I like cloud solutions as they keep me from having to worry about hardware, I still like the idea of a tape drive best.

Using external drives would work too, but if you need off-site then you probably need to by 7 or 14 of them so you can rotate them in and out just like you would with tapes.  You can look at a cartridge drive that basically uses a hard disk for media instead of a tape which is a compromise between the two.  The drive itself is fairly cheap although the media can be pricey when you get into higher capacities.

Your solution depends on the data -- and how critical it is.  For most non-critical data, backing up files of the size you are speaking of is no big deal.  However, your exact requirements will drive this.  You don't indicate the link speed or load level of the inter-floor connection.  If the link is very busy, then backing up in a reasonable timeframe may indeed be problematic.

Personally, I got rid of tape when my last drive failed -- over 7 years ago.  I do all of my backups to USB3 drives now.  Changing tapes or changing drives -- this is really the same thing.  However, I've found that the USB3 drives are vastly faster for both backup and random recovery.  As bas2754 indicates, you'd want a bunch of them for rotation purposes, just like with tape.  However, even buying fourteen 4TB drives at $130 each will likely still be far cheaper than buying a new tape drive and tapes.

If your data is really critical, though, then you may need something a bit better.  Nightly backup may still take an hour or so, and if you do need to recover a file, you're going back as many as 25 hours for the recovery.  You may wish to consider other solutions, such as a continuous data protection (CDP) hardware/software package, or perhaps a near-real-time replication solution.  These solutions will constantly migrate changes from your server to another location, ensuring that you never lose more than a few minutes of data if a restore is required.  

Of course, this doesn't eliminate the need for off-site storage, as a malware attack or vengeful user can still delete everything very easily, and it'll be wiped from the replication system at the same time.  However, in many cases, you can do the "normal" backup (to tape, USB drive, etc.) from the secondary server or data store and use that as your off-site storage.
