TSM provides a configuration parameter that enables backup data compression. If compression is enabled, the TSM client compresses the backup data before sending it to the TSM server. This decreases the amount of backup data sent to TSM server and the storage space it occupies at the TSM server.
To enable TSM compression for Sybase database backups, set the “COMPRESSION” parameter to “YES” in the TSM client configuration file (dsm.sys). The default value is “NO,” indicating no compression.
See the IBM Tivoli Storage Manager documentation.
