D
Busy File Wait
Specifies the duration (in seconds) of the quiet period that must occur before
NetBackup starts the open transaction manager. The quiet period is a period of
time during which no writes are being performed on the drives or volumes to
be backed up. The default is five seconds.
Maximum Cache Size
Specifies the maximum cache size (in megabytes) of the cache file. If the cache
file reaches this size and more cache is required, open transaction management
is turned off and the backup continues. However, relationships between the
backed up files can be lost because the snapshot is not used. The default
maximum cache size is 50 megabytes.
Busy File Timeout
Specifies how many seconds to wait for a quiet period to occur. If this time
expires, the backup proceeds but without open transaction management. The
default is 60 seconds.
Individual Drive Snapshots
Specifies that Open Transaction Manager take a snapshot of each drive and
back it up before proceeding to the next drive.
For example, assume that drives C and D are being backed up. Here, Open
Transaction Manager:
1. Takes a snapshot of drive C, backs it up, and discards the snapshot.
2. Takes a snapshot of drive D, backs it up, and discards the snapshot.
Open transaction management is enabled on only on one drive at a time,
depending on which one is being backed up. This mode is useful when it is not
necessary to maintain relationships between files on the different drives.
Global Drive Snapshots
Specifies that Open Transaction Manager take a snapshot that includes all
drives that are part of the backup and then back up the drives.
