Archive Device Aspect
specify the full path to the directory where data will be archived for example:
E:\archive (root directory is not a valid entry for disk drive).
Device Behavior and Overwrite Timeout
Device Behavior and Overwrite Timeout fields determine how archiving will
proceed when the current archive media (volume) becomes full. For Device
Behavior the choices are:
•
•
•
The Overwrite Timeout specifies the delay between the time when a media
becomes full and the time when the media can be re-initialized (overwritten). Set
this to the duration for which the data must be preserved. For example, to preserve
data for one year, set the Overwrite Timeout to 365 days. This means 365 days after
the LAST data has been written to the media, the media can be automatically
initialized by the archive service if the media is in the drive.
Use the pull-down list for this field to select the units: Hours, Days, or Weeks. Then
enter the number of units. The default is 0 which means infinite delay. To get
virtually no delay, enter a very small delay, for instance: 1 second. The Overwrite
Timeout is stored on the media, so removing the media from the drive and then
replacing it will not affect the Overwrite Timeout. Overwrite Timeout can be
changed via the Initialize dialog when a media is initialized for manual archiving.
When using archive backup
these guidelines for configuring Device Behavior and Overwrite Timeout.

Stop When Full (default, and recommended for MO drives) - Return device
full error when the device is full.
Advance When Full - Advance the active volume until one of the following is
found: a valid media with storage capacity, or a media that is not initialized. If a
volume that is not initialized is found, initialize the volume and start archiving
to it. If not, return device full error.
Wrap When Full (Recommended for Hard Disk devices) - First look for a
valid or not-initialized media. If a valid media is found, start archiving to it. If a
not-initialized media is found, initialize it and then start archiving to it. If
neither of these is found, look for a full media whose Overwrite Timeout has
expired, and with the earliest last archive time. Then reinitialize that media and
start archiving to it.
