I'm preparing to upgrade an existing Amanda installation.
It's been a while since I looked at what Amanda can do, since the existing
system "just works". I'm considering using virtual tapes, in some fashion
on the new system.
These leads me to a question (perhaps the first of several). Reading
through http://wiki.zmanda.com/index.php/File_driver It recommends putting
the virtual tape disk(s) on a different server than the holding disk(s). Am
I reading this correctly?
A different *disk* (could be on a different server yes) but this is no
absolute requirement. Just to avoid bashing the same disk with dumping
to holdingdisk and transferring to vtapes.
Deciding which disk is also a matter of not putting the backup on the
same disk as some of the DLE's that you try to backup: a diskcrash would
lose both.
If so, how would I access these disks? NFS seems like a slow way of doing
this.
Not always: NFS over gigabit ethernet is faster than many IDE disks.
Another example: an external disk connected to USB-1 can write at about
1 Mbyte/sec -- 100 Mbit networks are faster too.
