I'm wondering now if I can also create a full file hierarchy listing from
the incremental dump indecies? Amanda must somehow know which files from a
level 0 dump were deleted at the time of a subsequent incremental dump. I'd
like to check my restored volume against a list of files that were present
at the time of the most recent incremental dump.

Hi,

I've got a large xfs filesystem that had trouble and has undergone 
repair. Some inodes were disconnected from filenames. I've mostly been 
able to identify what's what from contents of the dir trees now named 
as inodes in lost+found. But I'd like to check the full file hierarchy 
to see what may be missing so I can do only targeted restore 
operations if needed.


I have an incremental backup performed just before the fs repair 
operation that moved some dirs into lost+found. I have a full backup 
from a couple months before that.


When I look at the index file for a DLE from the incremental backup, I 
see a lot of directory names with no filenames listed. It seems like 
the index may hold all directories within the DLE, even if no files 
were backed up from that dir during the run? Is that right?

yes
If so, I can recreate the directory hierarchy at the time of the 
incremental backup just from the index files from the incremental backup?


Yes, do a mkdir for each directory in the index file (the one which end 
with /).
