How to decompress the compressed backup files in BRTOOLS

Hi Friends,

I am new to SAP Technologies,.When i take offline backup,I took backup in compression mode instead of taking backup in Initialization of BRBACKUP tape volumes.Below i have attached the mistakes i did from log files.Please also tell me where the compressed files stored,bec i didnt mention any tape volumes and tape names.Can we decompress the backuped files without restoring?Please help me..

BRBACKUP options for determination of compression rates

1 - BRBACKUP profile (profile) ...... [initDV1.sap]

2 - Database user/password (user) ... [/]

3 - BRBACKUP run type (type) ........ [offline]

4 ~ Files for compression (mode) .... [all]

5 - Confirmation mode (confirm) ..... [yes]

6 - Query mode (query) .............. [no]

7 - Parallel execution (execute) .... [0]

8 - Additional output (output) ...... [no]

9 - Message language (language) ..... [E]

10 - BRBACKUP command line (command) . [-p initDV1.sap -k only -t offline -m all -e 0 -l E]

    Hi,

    you did not backup anything at all.

    -k only

    just calculates the compression ratio, so that brbackup is able to calculate the required tape swaps.

    So with "compress_only" no real backup had been done!

    Sorry, you'll have to redo that with "-k yes" and write to a device (-d tape)
