When using dump, level 0, to save the whole concerned partition :
$ dump -0f /path/to/target/drive / I'm said some folders are excluded (I guess, at least, tmp folder). I have not found more detail about it. What is the default excluded folder list please ?
Nothing is excluded. It's a level 0 dump, it dumps everything on that file system.
A level 1 dump would dump everything that was changed since the last level 0 dump.
A level 2 dump would change everything changed up to the last level 1 dump (if there was a level 1 dump, otherwise back to the level 0 dump).
Hence you could do incremental backups by doing a level 0, then 1, then 2 etc, until you do your next level 0 and start over again. If you need to restore, you'd have to restore your level 0, then 1 on top of that, then 2 and so on.
You could do differential backups by first doing a level 0, then doing level 1 backups, until your next level 0. This has the benefit of if you have to restore a file, or the entire file system, there's only 2 places to look, in either the latest level 1 or the level 0. You could save each of the intervening level 1 backups to be able to undelete a file that was newer than in the level 0 but older than the most recent level 1.
Note: If /tmp is on a different file system, then it is not dumped. Dump works on a file system bases. Hence if you have 3 file systems mounted, you will need to dump them 3 times. Furthermore, dump dumps the entire file system, you can't dump a directory. Use tar for that!
man dump? the-e option. I suggest you take a look at some Mint documentation to get a better understanding of what you want to do. eg. Minit Community Think also about your partition setup, do you have a separate partition for /home ? Try to work out a strategy. I get the feelingdumpisn't the right command for what you want, there were suggestions provided on your other recent questions. There are also topics in the Mint Forums that might help./tmpmounted on a separate filesystem?
