rot protection. For information, see Bit Rot Protection on page 62. Bit
rot protection can be set only when the LUN is created.

Select the Compression check box to enable data compression.
Compression saves storage space and increases the speed of data
transfers, but the compression and decompression processes require
additional resources. By default, the Compression check box is cleared.
Compression can be set or turned off only when the LUN is created.
Compression
Select the Auto-Defrag check box to enable automatic defragmentation.
When auto-defrag is on, after writing to a file, ReadyNAS OS consolidates
and rewrites portions of the file to reduce fragmentation.This reduces
or eliminates the need to periodically defragment the entire volume, but
because it occurs after every write it, can impact performance if a file is
written to very frequently. Examples of applications that make many
writes to the same file are databases, virtual machine images, and iSCSI
LUNs. If the share or LUN is used for these and similar applications,
auto-defrag might not be a good solution.
