.
This includes servers that contain lots of small files that are likely to slow down backup perform-
ance on the host (i.e., those found on Windows file servers and web servers), blade servers,
etc. Slower servers on the LAN typically interleave the backup through the media server and
go out to one tape drive. These are good candidates for VLS and D2D because you can con-
figure multiple virtual tape drives, disable multiplexing, and then backup each slow server in
parallel (with multiplexing disabled the restores will run faster). See
Multistreaming, and
variety of ways, including using the tools found at in the Software Downloads section of the
Developer & Solution Partner Program web page: http://h21007.www2.hp.com/dev/.
• Data that you want to electronically off-site using deduplication enabled replication (and thus
must be backed up to a local VLS or D2D which can then replicate the data automatically to
another VLS or D2D in another site).
• Archive data.
• Look for aggregate bandwidth bottlenecks between hosts and backup devices. One common
bottleneck is the LAN bandwidth (for LAN backups), so identify which of the larger application
