If you are soft linking Volume names, yes, which probably means fixed
Volume names pre-labeled. If you are trying to soft link directories
(i.e. disk "Archive device"), I'm not sure. I use this technique to have
Bacula disk
backup where the total data of all the Volumes is larger than a single hard
disk.
Example:
In directory /files/havana an "ls -l"
total 76652132

Note, /files1/havana is a different hard disk. Bacula only knows about
/files/havana. From SD conf file:
Device {
Name = FileStorage
Media Type = File
Archive Device = /files/havana
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = no;
AlwaysOpen = no;
}
Interesting. You can see the date when I added the second harddisk, and
Bacula has just continued backing up and recycling ever since with no
manual intervention other than me doing 1 or 2 upgrades.
