Default Migrate Policy
Default Clear on Erase Policy
Description
Number of slots in the virtual loader. Each slot contains a VTC.
Select one of the following:
• Automatic – newly created virtual tape cartridges are automati-
cally archived. (Default) (Recommended)
• Do Not Archive - newly created virtual tape cartridges are not
automatically archived,
See Appendix A for an explanation of Archive.
• After Exiting Write Mode - when a host backup operation to a CP
3100 VTC completes, the backup software may leave the VTC
loaded in the virtual tape drive (VTD). In this case, the CP 3100
begins the archive process after the listed amount of minutes
expires after the backup software stops writing to the VTC. A
change in this value affects all VTCs in the CP 3100.
• After Unloading Cartridge - when a host backup operation to a
CP 3100 VTC completes, the backup software may unload the
VTC and place the VTC back into the empty slot. In this case, the
CP 3100 begins the archive process after the listed amount of
minutes expires after the backup software moves the VTC back
into the virtual loader. A change in this value affects all VTCs in
the CP 3100.
A migrate operation removes a virtual tape cartridge's data from the
storage pools after the data has been archived successfully. Select
one of the following:
• Automatic — data written to newly created virtual tape car-
tridges is automatically migrated. (Default)
• Do Not Migrate - data written to newly created virtual tape car-
tridges is not automatically migrated.
See Appendix A for an explanation of Migrate and Archive.
Data sent to a virtual cartridge from host backup software is physi-
cally stored on the CP 3100 hard drive(s) and logically formed into
Storage Pools. The data stored within the virtual cartridge can be
erased (overwritten) when the virtual cartridge is removed (see "Per-
forming Advanced Operations" on page 70).
• Clear on Erase - overwrite the data on disk that was contained
within the virtual cartridge when the virtual cartridge is removed.
• Do not Clear on Erase - the data on disk contained within the vir-
tual cartridge is not overwritten when the virtual cartridge is
removed. (Default)
Note: If Clear on Erase is set, an erase operation can take several
minutes to complete. During this time, do not use the CP 3100 to per-
form new backup-and-restore operations.
