Backup Central

Hello,

A recent experiment produced an outcome
that seems at odds with the documentation
on the "portable" keyword as described at

http://bacula.org/5.2.x-manuals/en/main/main/Configuring_Director.html#9197

The documentation states that the default
is "portable=no" and implies that Windows
files restored to *nix system will be
unusable (perhaps because NTFS attribute
streams could be included in the file data).

However after restoring a few Windows files
on a Linux system, I observed that the
content of the files appears to exactly
match the originals. No "portable" keyword
appears anywhere in the FileSet specifications.

Can anyone shed some light on what specific
meaning of "portable" is and what would be
broken about Windows data restored on a
*nix system (other than missing NTFS
file attributes) when portable=no is
in effect?

Running version 5.2.3.

Thanks

Dug into into the code and figured it out.

1) I was correct in thinking Windows backups
include the extended attribute "streams" as
Microsoft calls them.

2) Looks like the restore code detects when
the backup is a multi-stream Windows backup
and when the Windows API is not present,
and at that point sets portable mode
and presumably causes the alternate
stream data to be ignored so the regular
file data is restored correctly. I didn't
follow the string all the way to the end
in the logic, but am assuming that since
it works that's what it's doing.
