Place this option at the beginning of your dsm.sys file before any server stanzas.
The compression option compresses files before you send them to the server. Compressing your files reduces data storage for backup versions and archive copies of your files. It can, however, affect TSM throughput. A fast processor on a slow network connection benefits from compression, but a slow processor on a fast network connection does not. Use this option with the backup-archive client option, compressalways.
If you specify compressalways yes, compression continues even if the file size increases. To stop compression if the file size grows, and resend the uncompressed file, specify compressalways no.
If you specify compression yes, you can control compression processing in the following ways:
This option controls compression only if your administrator specifies that your client node determines the selection.
