flashcopy backup completes, but not after issuing a flashcopy
stop during the flashcopy backup.
2. For flashcopy backup to function properly, each target partition
must have the same file system type as its source partition.
3. Do not attempt to write to the target partitions until the backup
process is completed.

where:
v
controller is the ServeRAID controller number (1–12)
v
source is the source partition number
Note: Use the flashcopy map function to correlate the
ServeRAID logical drive number to the operating system
drive partition number.
v
target is the target partition number
Note: Use the flashcopy map function to correlate the
ServeRAID logical drive number to the operating system
drive partition number.
v
options is an optional parameter that includes the following:
– POLL displays the progress of the backup function.
– FORCE creates a flashcopy of a source partition that is the
boot partition and contains open files or contains a memory
paging file.
Note: Using the FORCE option will not guarantee file
consistency between the source and target partitions.
– NOPROMPT overrides the user prompt.
flashcopy nobackup
Use the flashcopy nobackup function to create a quick snapshot
of the source partition data on its target partition. Once the
snapshot is created, the source partitions are ready for immediate
use. Each target partition will contain a snapshot of its source
partition data that existed at the exact time you issued the
command. A link between each source partition and its target
partition will exist until you issue the flashcopy stop function. Once
you issue the flashcopy stop function, each target partition
contents are no longer valid. The flashcopy nobackup function is
useful if you want a snapshot of your data to perform a tape
backup.
You can use the flashcopy map function to determine the partition
numbers and if they are available for the flashcopy nobackup
function process.
Notes:
1. Only one flashcopy nobackup link (involving up to four source
and target partitions) can exist on a ServeRAID controller. If a
