Hello,

I
accidentally deleted some parts of a filesystem that is backed up
periodically, but I do not know exactly which files have been dropped
(rm -rf ....,and CTRL C...)
So, Is there is a way to compare what changed from the last backup and
the actual disk filesystem content in order to restore only these files
in a folder ?
Why do you want to do that?
I think a simplest way to recover from above situation is to restore
all files from a backup to original location with option for never
overwrite an existing files. Something like this:
Using Catalog
"MyCatalog"
Run Restore job
JobName:
RestoreFiles
Bootstrap:
/var/bacula/working/debian-dir.restore.3.bsr
Where:
Replace:
always
FileSet:
Full Set
Backup Client:
debian-fd
Restore Client:
debian-fd
Storage:
File
When:
2011-05-31 17:51:22
Catalog:
MyCatalog
Priority: 10
Plugin Options:
*None*
OK to run?
(yes/mod/no): mod
Parameters to
modify:
1: Level
2: Storage
3: Job
4: FileSet
5: Restore
Client
6: When
7: Priority
8: Bootstrap
9: Where
10: File
Relocation
11: Replace
12: JobId
13: Plugin
Options
Select parameter to
modify (1-13): 11
Replace:
1: always
2: ifnewer
3: ifolder
4: never
You can choose recommended option: never. If some file exist on
filesystem (thus was not deleted) it will be skipped from restoration
and you will restore everything else.

Hi !
Thanks for your reply, this seemed a nice solution....
However, here is what had happened with our very very badboys network's
administrators :
a) They restored 159Gb of data backed up on monday (slow, need some
disk storage, but it was available)
b) they used rsync as follow : !!!!
rsync -avr x y
c) today everybody was happy when seeing they had LOST three days of
work....
and since the tape was running to restore ... no backup until now....
So, now I have some more questions :
1) Using a tape is slow, is it possible to use a disk storage as backup
device with bacula ??????
2) if 1) is possible, can we use concurrent accesses to the catalog in
order being able to restore some data , while we are backing up other
ones ????
