Optimized duplication
failover
Number of optimized
duplication attempts
Storage lifecycle policy
retry wait period
Caution: These settings affect all optimized duplication jobs; they are not limited
to optimized duplication to a Media Server Deduplication Pool or a PureDisk
Deduplication Pool.
You can configure several optimized duplication copy behaviors, as follows:
Optimized duplication failover.
By default, if an optimized duplication job fails, NetBackup does not run the
job again.
Number of optimized duplication attempts.
You can specify the number of times NetBackup retries an optimized
duplication job before it fails the jobs.
Storage lifecycle policy retries.
If the optimized duplication job is configured in a storage lifecycle policy,
NetBackup retries the job three times.
Caution: These settings affect all optimized duplication jobs, not only OpenStorage
optimized duplication jobs.
Configuring OpenStorage optimized duplication behavior
The default NetBackup behavior is to use optimized duplication
between the source and the target storage systems that support
optimized duplication. If an optimized duplication job fails,
NetBackup does not run the job again.
You can configure NetBackup to use normal duplication if
optimized duplication fails.
The default is three attempts. You can specify the number of
times NetBackup retries an optimized deduplication job before
it fails the jobs.
If the optimized deduplication job is configured in a storage
lifecycle policy and the job fails, NetBackup retries the job three
times. If the job is unsuccessful after three tries, NetBackup
waits two hours and then retries the job. You can change the
wait period.
