Cleanup by
DataClass
A DataClass group parameter specifies the default cleanup
action. A Cleanup policy can be:
• Completely disabled.
- Files can be excluded from clean-up. Use this only for
frequently accessed files.
• Immediate truncation following the storage policy.
- Valid only if all copies defined by the file’s attributes
are stored. If all copies are not made, the cleanup
action does not occur, because that file is not eligible
for cleanup.
- The file remains on disk after storage policy until the
fspolicy -t command is invoked for the file
system on which the file resides, and the file is eligible
for truncation.
• Truncated when cleanup policy determines that disk space
is necessary.
- The file remains on disk after storage policy until the
fspolicy -t command is invoked for the file
system on which the file resides, and the file is eligible
for truncation.
Copy
Secondary Files
For protection of media-based files, secondary file copying is
provided. If enabled for a DataClass group, files automatically
have a secondary copy maintained on a separate media.
