How to enable NetBackup compression
Table: Tips on how to enable NetBackup compression
Type of compression | How to enable |
|---|
Client compression | Select the compression option in the NetBackup Policy Attributes window. |
Tape drive compression | Enabling tape drive compression depends on your operating system and the type of tape drive. Check with the operating system and drive vendors, or read their documentation to find out how to enable tape compression. Tips: With UNIX device addressing, these options are frequently part of the device name. A single tape drive has multiple names, each with a different functionality built into the name. (Multiple names are accomplished with major and minor device numbers.) If you address /dev/rmt/2cbn on Solaris, you get drive 2 hardware-compressed with no-rewind option. If you address /dev/rmt/2n, its function should be uncompressed with the no-rewind option. The choice of device names determines device behavior. If the media server is UNIX, there is no compression when the backup is to a disk storage unit. The compression options in this case are limited to client compression. If the media server with the disk storage unit is Windows, and the directory that is used by the disk storage unit is compressed, note: compression is used on the disk write as for any file writes to that directory by any application. |
