Business Copy XP user guide for the XP10000/XP12000 41
• External Storage XP. BC operations can be performed with External Storage XP operations to create
pairs with the external volumes.
Combining BC and Continuous Access XP Journal operations
Continuous Access XP Journal volumes can be assigned to BC pairs, and BC volumes can be assigned to
Continuous Access XP Journal pairs.
BC and Continuous Access XP Journal can function together in the same Local disk array to provide both
internal and remote backup for your important data.
NOTE:
• A primary volume (P-VOL) of Continuous Access XP Journal means a primary data volume of
Continuous Access XP Journal. A secondary volume (S-VOL) of Continuous Access XP Journal means a
secondary data volume of Continuous Access XP Journal.
• Combining BC L1 and L2 pairs with Continuous Access XP Journal volumes is allowed. Continuous
Access XP Journal considers node and leaf volumes as secondary volumes (S-VOLs).
The configuration shown in Figure 15 is an example of a volume that functions as both a Continuous Access
XP Journal
P-VOL and a BC P-VOL. This configuration allows you to:
• Use BC to provide on-site backup copies of Continuous Access XP Journal P-VOLs
• Use Continuous Access XP Journal to provide remote backup copies of BC P-VOLs

Continuous Access XP Journal: Shared P-VOL and P-VOL
The configuration shown in Figure 16 is an example of a volume that functions as both a
Continuous Access
XP Journal
S-VOL and a BC P-VOL. This configuration allows you to use BC to provide remote copies of
Continuous Access XP Journal S-VOLs.

Figure 17 is an example of a volume that functions as both a Continuous Access XP Journal P-VOL and a
BC P-VOL, while the S-VOL of the same
Continuous Access XP Journal pair also functions as the P-VOL of
another BC pair. This configuration allows you to:
