My experience in the past three years showed me that the modern tapedrives are really amazing devices. With 'modern' I mean the AIT-3, SDLT and LTO technologies as these are the drives I've experience with.
First, for small to medium sized bussinesses these drives hold all data on a single...
Seen quite a few errors on tapedrives connected to a 29160. Three cases were solved by using a SE terminator on the drive (so the bus switched back to SE speeds, still fast enough for the drives) and one customer exchanged the 29160 for an older 2940 UW controller.
First thing to do is...
LTO is a very fast medium. Be sure to connect it to a dedicated controller, and let it be a *fast* controller. A SCSI-2 (10/20MB/sec) won't do, you really need an Ultra (20/40MB/sec) at least.
Depending on the data a LTO can soak up more than the bus can deliver if you have hardware compression...
Both types of drives (you're talking about DLT7000 and DLT8000 actually) use the same type of cartridge, a DLT Type IV.
A new, unused tape can be used on both drives without problems. However, a tape used/written to in a DLT7000 will be recognized in a DLT8000 as such, and cannot be written to...
As you have 5 PC's all shared with each other and no dedicated fileserver, Arcserve may not be the program you want. It can do a backup of the system it is running on and do a backup of the shared directories/drives, and with added Agents it also will do full backups of connected workstations...
