Key Considerations 133
To locate a backup file you will need to know:
■ The IP address of the source device at the time the backup was made.
■ The date and time of the Device Backup operation that created the
backup file
All backup files have the file extension
.xml, and are named according to
the scheme shown in Figure 64
:
Figure 64 Backup File Name Format
When deleting unwanted backup files you should take care to also delete
any auxiliary files referenced by the backup in order to conserve hard disk
space. Auxiliary files to a backup have the same filename as the backup
file but a different extension (e.g.
bak, unit1, module*)
Key Considerations The following section provides assistance when using Backup, Restore
and Setup.
How Backup Files are
Discarded
Before the Device Backup operation saves a backup for a device, it
performs a consistency check. The consistency check looks for any
existing backups that conflict either with the physical identification or the
physical configuration of the current device. Any existing backups that
fail this consistency check will be discarded before a new backup is saved.
This happens if:
■ There are existing backups associated with the physical identification
of the current device but the physical configuration stored in the
existing backups does not match the physical configuration of the
current device.
