I don't have access to the SysAdmin magazine, so I could not read the
article. But from what you write about it:

I chose to create the snapshots by cron, mount them, share them and
have amanda back them up. Then I leave them mounted and shared the
whole next day. This way users have access to the last backup and can
restore files by themselves. This has saved us quite a lot of work.
I also use the automounter to have the snapshots mounted anywhere
automagically:
local filesystem: /home, /home1
Snapshot: /snapshot/home, /snapshot/home1
automount point: /homes/<host>, /homes1/<host>
snapshot mount point: /snapshots/homes/<host>, /snapshots/homes1/<host>
By naming the snapshots this way, I can easily prefix a users home
directory with "/snapshots" and have instantly access to his home the
day before. So creation of a personal snapshot samba share is really
easyly done:
[homes]
comment = Home Directories
read only = no
browseable = no
inherit permissions = no
[my_snapshot]
comment = Home Directory from yesterday
path = /snapshots/%H
read only = yes

Christopher
