restore operations work on an entire disk, partition, or LUN. You might not be able to back up a subset of
files or restore a single file. If you can restore a single file, the restore process will be slow.
Database backup performance will vary. To improve performance when backing up data from a database:
•
Use specific backup agents for the database
.
•
Use the latest versions of the databases.
•
Do not back up individual mailboxes.
•
Do not back up specific records or do a record-by-record backup.
•
Do not back up when the database is in heavy use.
8.4.6 Connection from the Archive/Backup Host Server to the Library
For best performance, the connection from the host server to the library must have enough bandwidth to
keep all of the tape drives streaming. Current LTO tape drives take advantage of some of the fastest
interfaces available so the type of interface used to connect the library to the host server is not likely to be
the cause of a performance issue. However, issues with cables and connectors can limit performance.
Do not exceed recommended cable lengths.
