Compression and encryption backup processing
This topic lists some items to consider if you want to include specific files or groups of files for compression and encryption processing during a backup or archive operation.
- You must set the compression option to yes to enable compression processing. If you do not specify the compression option or you set the compression option to no, Tivoli® Storage Manager does not perform compression processing.
- Tivoli Storage Manager processes exclude.fs, exclude.dir,
and other include-exclude statements first. Tivoli Storage Manager then
considers any include.compression and include.encrypt statements.
For example, consider the following include-exclude list:
exclude /home/jones/proj1/file.txt include.compression /home/jones/proj1/file.txt include.encrypt /home/jones/proj1/file.txt
Tivoli Storage Manager examines the exclude /home/jones/proj1/file.txt statement first and determines that /home/jones/proj1/file.txt is excluded from backup processing and is, therefore, not a candidate for compression and encryption processing.
- Include-exclude compression and encryption processing is valid for backup and archive processing only.
