Viewing the compression ratio
The bptm logs provide information of the compression ratio of your data after the backup is taken in the cloud storage. The compression ratio is calculated by dividing the original size with the compressed size. For example, if the original data is of 15302918144 bytes and is compressed to 7651459072, then the compression ratio is 2.00.
To view the compression ratio
- Note down the bptm PID of the backup job.
- Open the
bptm.logfile. The log file resides in the following directories:UNIX
/usr/openv/netbackup/logs/
Windows
install_path\NetBackup\logs\
- Search for the bptm PID instance.
The following lines provide the compression ratio information according to the image format:
date:time <PID> <4> 35:bptm:<PID>: media_server_IP: compress: image image_name_C1_F1 compressed from data in bytes to data in bytes bytes, compression ratio ratio_value
date:time <PID> <4> 35:bptm:<PID>: media_server_IP: compress: image image_name_C1_HDR compressed from data in bytes to data in bytes bytes, compression ratio ratio_value
