HP Storage StoreOpen Standalone for Microsoft Windows User Guide

• Check and repair volume: Select this option to check the volume for consistency.
If you suspect the volume was not updated properly due to a power outage, select
the Perform deep recovery if necessary option, which will attempt to verify and, if
◦
necessary, recover from a missing End Of Data (EOD) marker. This may take a long
time and may result in the loss of unindexed data blocks written since the last good
index.
◦ If it is important to try to recover those unindexed data blocks, select the option
Attempt to save any unindexed data blocks. The utility will try to save the blocks to
a new folder _ltfs_lostandfound.
NOTE: You need to identify and manipulate any recovered blocks manually, since
there will be no identifying details (because they were not in any index).
• Rollback cartridge contents to previous state: Select this option if you want to change the
view of the cartridge contents to a previous point in time. There are two choices:
◦ Keep all history to allow potential roll forward in the future: The default is to roll
back the contents as viewed in the index, but not erase any data — on other words,
the view of the contents is changed, but the actual contents are unchanged. This
allows for a future operation to “roll forward” the contents again, recovering changes
that occurred since the rollback point. Note that no storage space is freed up by this
option.
◦ Permanently erase all files after rollback point: Roll back and erase the history. In
this case, any changes since the rollback point will be lost irretrievably, so be sure
that this is what you intend. This option will free up the storage space used by those
changes.
If you opt to Rollback cartridge contents, an additional window is presented where you
will be able to select a rollback point from those on the cartridge. Click Start scan to
initiate a scan of the entire volume, looking for previous index points stored on tape. This
operation may take many minutes or even several hours. When complete, the window
is refreshed to show the available rollback points. For example:
Using the CheckWizard 19
