Facing issues with tar and gzip !
Hi,
I am trying to :-
(1.) Tar the file and then
(2.) Gzip it !

HTML Code:
Tar command :-
 
tar -cvf BLUESTAR_Archive.log_$(date +%y_%m_%d_%H_%M).tar  /app/local/XXX/XXX/XXX/logs
 
 
Gzip command :-
 
Gzip  /app/local/XXX/XXX/XXX/logs/BLUESTAR_Archive.log_$(date +%y_%m_%d_%H_%M).tar
Bothe of these commands are working fine but the problem is regarding the file size.

After doing the tar and gzip operation the size of the file keeps on increasing which is expected to be less or same as the previous gzip files.

HTML Code:
Extract :-
 
-rw-r--r--  173471   Jul  9 13:03 BLUESTAR_Archive.log.log_12_07_09_13_03.tar.gz
-rw-r--r--  318456   Jul  9 13:14 BLUESTAR_Archive.log.log_12_07_09_13_14.tar.gz
-rw-r--r--  1031131 Jul  9 13:15 BLUESTAR_Archive.log.log_12_07_09_13_15.tar.gz
-rw-r--r--  1523045 Jul  9 13:16 BLUESTAR_Archive.log.log_12_07_09_13_16.tar.gz
-rw-r--r--  3020915 Jul  9 13:18 BLUESTAR_Archive.log.log_12_07_09_13_18.tar.gz
The size of the parent file doesn’t increase beyond 2000000 !!!!!

I am not able to understand that why the size of the files after gzip keeps on increasing when the size of the parent file doesn’t increase beyond 2000000 !!!!

When I delete the older logs the gzip again starts behaving in the same fashion i.e the 1st file of less size and gradually the size of files increases like the above one .
I am very surprised by this behavior !

Could anyone please help me to understand the problem or is there something wrong with my logic or way of doing it !!!!

Is there any other command similar to tar and gzip ??

Please help.

Regrads.
