About incremental backup
 
Hi folks,

About .tar.gz and .tar.bz2 files and incremental flag "-g" and "-G"

I have a directory, say dirA, of 5G approx in size including hundreds of subdir and files. Can I apply "-G" flag to do incremental backup.

For example:
an old compressed file dirA.bz2 already exists

Can I run;
$ tar -jcpf -G dirA.bz2 --same-own /path/to/dirA

to do incremental backup? If possible it will save lot of time.

Will subdir/file already removed from dirA be removed from the new tarball dirA.bz2 as well?

TIA


B.R.
