Is amanda suitable for a single server backup?

[Howard Zhou]

If I have a single server to backup with 4Gb of data backed up to a 40-80Gb
tape without a tape changer, would amanda do the job? To my understanding,
amanda does append to a tape. Without appending, you have to put in a new
tape everyday for a small amount of incremental backup data on 40-80Gb tape
(what a waste) plus manual process.

Is there any plan to support appending to tape in a future release?

Is there any other free backup system which supports this feature?

Thanks in advance.
