['chris']

hi

I do backups of my webserver data with tar Pcj

my colleague is doing with tar cvjf

what's really different ?

kind regards

v stands for verbose output

f stands for use a file

some versions of tar default to a file of /dev/rmt/0m if you don't use the -f parameter and specify a file

P I believe stands for preserve permissions and/or Pathes.

Hi
tar Pcj means use absolute paths, of course create, and j zips through bzip2.
tar cvjf means still create, verbosely lists files created, zips through bzip2 and f stands to precise archive file or device to use.
So the main difference is that your colleague uses a more verbose output than you do, and designate the device or the file archive name to use, and you use absolute paths whereas he doesn't...

From France Chris (don't know if it's a good place to be or not, but computer don't make that difference),
teaching linux for years, and spending my time discovering new things !
And enjoying your questions always precise and well targeted.
As for your question to Steve, using absolute paths is a good idea, verbose is not useful if you know what you do, but I still like seeing the system confirming that everything goes the way I want, and f is useful only to precise archive to use, which doesn't seem to be a necessity for you (but if you precise it thenafter or before, adding it at that point wouldn't do any harm).
So a tar Pvcj could be workable.
Whatesoever, your way is efficient and working.
BTW, I between Valence and Gap, where do you leave in Switzerland ?

I don't think it makes a difference Chris.

I use tar cvf to build or tar rcf to update and tar xvf to lay it down on the other machine.

So long as I position that tar file correctly everything works out.
