If there's a limitation, I've never seen it.

NetBackup does have the checkpoint ability but it's not at the saveset
level - it's time and file based so if you have a single 500GB volume
and you fail 4 days into your backup, you can continue from 15 minutes
back. The time period is configurable on a per policy basis but you
can't restart half a file - if the backup was a single 500GB file, you'd
be restarting from the beginning.

True for Netbackup. I don't know about Legato. Netbackup has multiple
licenses:
- master server
- media server
- SAN media server
- number of drives
- shared storage option (multiple SAN hosts sharing the same
drives)
- clients
- Advanced client for special features

True. Clients, however, are pretty cheap. Windows hosts are really
tiered too - it's just that the tiers are based on number of cpus. Tier
1 for a single cpu, tier 2 for 2 cpus, tier 3 for 4 cpus (I think). I'm
backing up my entire VMScluster with a single Tier 1 VMS license.

True. For some features (snapshot, Oracle block level incremental,
flashbackup), you may want the Advanced Client.

True. It doesn't handle things like Oracle or Exchange though - you
need special options for that.

It's tolerable. Not great but not too bad either. I prefer a mix of
command line and GUI with the majority of the work being done in the
command line on our Unix master server.
