Hello,
A hypothetical scenario.
I have Bacula 9 running on Debian 9 and writing to LTO-7 tapes
(Quantum-Ultrium).
Can I read these tapes elsewhere without Bacula?
Normally that would require tapes to be formatted to LTFS.
Can Bacula write to LTFS tapes or can it only use own native data
structure?
Would browsing and copying data require Bacula tools (such as bls and
bextract) installed?
Does it matter if I write in Linux and read in Windows or Mac?
Can LTFS and Bacula work closely together or are they mutually exclusive?
Bacula does not format the tapes as LTFS. However, Bacula can write to
disk volumes. It should certainly be possible to format and mount the
tape outside of Bacula using, say LTFS-SDE, and then configure Bacula to
write "disk" volumes to that mountpoint.
The answer depends on what you mean by "read". You could write Bacula
disk volume files to a LTFS mountpoint. The tape could later be mounted
on another system and those volume files could be read as any other
file. But to extract the internal contents of the Bacula volume files,
you would need Bacula or a tool of some sort that can interpret the
Bacula volume file. This is true of any file format. You could also
write PDF files to a LTFS tape and later restore them somewhere else,
but you couldn't view the PDF content without a PDF viewer.
