Hi,
Last week we needed to do a recovery of an entire drive of a windows
system, because microsoft's SMS had wiped it clean.
So we started networker user, selected the drive and started to recover.
For this it needed a full and a couple of incrementals.
After the recover was complete some users complained that not all files
were there. With the 'change browsetime' option we were able to recover
the files/directories.
The problem seems to be in directories which have been renamed/moved in
the period between the full and the last incremental.
to reproduce:
See the following structure:
E:\
map1\
file1.txt
file2.txt
map2\
file3.txt
file4.txt
Now do a full backup of E:
- Now rename map1 to map1a
- Create a new file 'file5.txt' in map1a
- Create a new directory 'map3' and move 'map2' to 'map3'
This means the structure has become:
E:\
map1a\
file1.txt
file2.txt
file5.txt
map3\
map2\
file3.txt
file4.txt
Now do an incremental backup of E:
Now start the 'networker user', choose 'recover' and choose E:.
You'll see map1a and map3. This was the situation of the last
incremental backup, so far so good.
However if you select map1a, you'll notice that only file5.txt is
visible and selectable. file1.txt and file2.txt are not selectable.
Also map3 is without content, buth map2 should be in there.
the command line tool 'recover' has the exact same problem. I tried
different versions of client and server software, all with the same
problem.
Also Linux clients seem to have the exact same problem.
This way it's impossible to do a reliable restore of the last situation,
because there are files missing!
And there I was, thinking the purpose of backup software was to be able
to do a reliable recovery. What was I thinking?!? ;-)
Any thoughts anyone?
greetings,
Dennis
