Hi,
	We are thinking of getting an exabyte stacker for a Sun 4/330 to
act as a backup server. 

- Has anyone had any experience with using a stacker?

- In general, is software to change tapes, etc. bundled with the stacker?

- How reliable are they?

- What is their transfer rate (eg how long would it take to back up a
  1GByte filesystem)? 

- Any experience with the newer 5GByte exabytes as opposed to the 2GByte
  systems?

	Second question, does the SysVR4 "backup" system allow backing up onto
remote devices (eg : an Exabyte stacker on a Sun4/330) and if so what is 
the mechanish, via RFS mounting the remote device or by some other mechanism?


Thanks in advance.
