6.5 HP StoreAll OS User Guide

default retention period is set to zero, the files become WORM. If the default retention period
is set to a value greater than zero, the files become WORM-retained.) To use this feature,
check Set Auto-Commit Period and specify the time period. The minimum value for the
autocommit period is five minutes, and the maximum value is one year. If you plan to keep
normal files on the file system, do not set the autocommit period.
• Enable Data validation. Select this option to enable data validation. When data validation is
enabled, checksums are created at the time of the first validation scan for files that have
transitioned to a WORM, a WORM-retained or a WORM-hold state. This checksum is used
by the validation scan to compare the newly computed checksum.
NOTE: Keep in mind the following:
◦ Express Query must be enabled to enable data validation. If data validation is not enabled,
checksums for WORM, WORM-retained or WORM-hold files are not generated.
◦ If a file system is enabled for continuous remote replication and wormed files, data
validation scans for the wormed files are not replicated to the target file system. To resolve
this, you must enable data validation on the target file system. Note that this will recalculate
the hash sums on the target file system.
As of StoreAll version 6.5, validation scans no longer trigger the WORM transition for
autocommitted files. This task is now performed by the Filesystem Metadata Cleaner task,
which is enabled along with Express Query. The Filesystem Metadata Cleaner task runs daily
at 1:30 a.m. local time by default.
• Schedule Data validation. Select this option to schedule periodic validation scans on the file
system. Use the default schedule, or click Modify to open the Data Validation Scan Schedule
dialog box and configure your own schedule.
To enable data retention on an existing file system, created with StoreAll version 6.0 or earlier,
follow the steps to upgrade the file system as described in the HP StoreAll Upgrade Guide. Then,
configure the file system retention profile as described in the steps provided earlier in this section.
