SnapMirror creates snapshots on the source volume, which are copied to the mirror.
The snapshot name is in the following format:
filer_volume
.
number
filer is the host name of the destination filer.
volume
is the name of the destination volume (the mirror).
number
is the number for the snapshot starting at 1.
SnapMirror automatically deletes old snapshots that are no longer necessary for data
replication.
([DPSOH
The following example describes the snapshots that are created on the source vol-
ume and copied to the mirror.
In this example, data is replicated from
/vol/vol1
of filerA to
/vol/vol2
of filerB.
To create a baseline version of a mirror, filerA creates a snapshot file named
/vol/vol1/
filerB_vol2.1
on filerA. All snapshots in
/vol/vol1
of filerA, including
/vol/vol1/
filerB_vol2.1
, are transferred to
/vol/vol2
of filerB.
For example, the
snap list
command on filerB generates the following display after
/vol/vol1/filerB_vol2.1
is transferred from filerA to filerB.
