take 40 minutes create the matching 1000 cartridges on the source device and complete the
"Adding Cartridge" operations for all 1000 cartridges.
Up to Date. The source virtual cartridge is fully synchronized with the matching target cartridge
(the mirror is in sync).
Waiting for Backup Data. Waiting for the backup application to update the source virtual
cartridge (append or overwrite with new backup data). Note that replication is only performed
on backups that occur after the replication configuration is performed, so even if there are
existing backups on the source virtual cartridges when replication is configured they won't
replicate until they are updated.
In Use. The source virtual cartridge has been loaded into a virtual tape drive (this always
overrides any replication job which will be restarted once the cartridge is unloaded from the
drive).
Once a source virtual cartridge has been modified with new backup data, then the cartridge is
queued for replicating with the following states:
Backup Postprocessing. The source virtual cartridge has been modified but replication is
waiting for the deduplication to finish analyzing it to determine what data is unique in the
new backup. (All data is unique if this is a new backup, if deduplication was disabled in the
GUI for this backup, or if the backup data type is not supported by deduplication.) Virtual
cartridges that have been pre-formatted by the backup application (such as HP Data Protector)
but have not been used yet for backups will also appear in this state.
Out of Sync. The source virtual cartridge has been modified (last mirror date on the source
virtual cartridge is newer than its last write date) and is ready for replication (deduplication
has finished analyzing it) but is currently outside of the replication window policy defined in
the echo copy pool. The "Copy Now" task can be used to manually override the replication
window.
Mirror Scheduled. When the replication window starts, the modified source virtual cartridge
is queued up for processing. If a source virtual cartridge is modified within a replication
window then it will be added to the queue as soon as the backup postprocessing is complete
(it does not have to wait until the next window starts).
The queued cartridges are then processed, running as many concurrent replication jobs as allowed
based on the "max jobs" setting in the replication target on the target device (the default is to run
four replication jobs concurrently). You can view the active jobs in the replication job reporting
screens but the following source cartridge states also show the progress of an active job:
Mirror Preprocessing. The active replication job is gathering together all the data needed for
the replication transfer including the unique data (the deltas) on the cartridge and replication
metadata.
Mirroring. The active replication job is transferring the data (deltas plus metadata) over the
LAN/WAN link to the target device.
Mirror Postprocessing. The active replication job has successfully transferred the delta data
over to the target device and is now converting it to a fully intact cartridge on the target device
(to provide maximum restore performance).
Mirror Broken. This state shows an unexpected error occurred while running the replication
job. You can use "Restart Broken Mirror" to attempt to recover from the error.
Restoring. This state is when a Restore over LAN/WAN is being performed.
