Archiving Logs

I've logs that I gather and put into a directory named /home/status. There's a script that runs commands and directs the output to files within this directory. The script runs every hour of every day. The output is dumped into a directory akin to "070101/", which means 2007-01-01. Each directory would have 24 files. I periodically archive these (by year) into tar.gz files.

Here's how the directory looks:

root@starchild:/home/status/070101# ls
070101.00.starchild.txt 070101.04.starchild.txt 070101.08.starchild.txt 070101.12.starchild.txt 070101.16.starchild.txt 070101.20.starchild.txt
070101.01.starchild.txt 070101.05.starchild.txt 070101.09.starchild.txt 070101.13.starchild.txt 070101.17.starchild.txt 070101.21.starchild.txt
070101.02.starchild.txt 070101.06.starchild.txt 070101.10.starchild.txt 070101.14.starchild.txt 070101.18.starchild.txt 070101.22.starchild.txt
070101.03.starchild.txt 070101.07.starchild.txt 070101.11.starchild.txt 070101.15.starchild.txt 070101.19.starchild.txt 070101.23.starchild.txt
root@starchild:/home/status/070101#
Here are the archives I currently have:
root@starchild:/home/status# du -h sensorstat_logs-200*
748k sensorstat_logs-2005.tar.bz2
3.5M sensorstat_logs-2006.tar.bz2
7.3M sensorstat_logs-2007.tar.gz
root@starchild:/home/status#

This is a listing of the month of January (unarchived):

The command I use to archive the directories within /home/status is:

tar cvjfp sensorstat_logs-2007.tar.gz .

c - creates the archive
v - verbose output once the command is run (this isn't needed, but I like to see what the command is doing.
j - compresses archive
f - uses a file name
p - preserves permissions of files within archive


The "." at the end of the command directs the command to archive everything within the current directory.

Once the files are archived, I can get rid of them using the 'rm' command to free up some space.

I thought all of this would be cool to share...
