NetBackup Storage Lifecycle Policy (SLP) is a powerful feature used not only for image duplication but also for disaster recovery purpose. In this post you can find answers for questions related to SLP that I received under some posts that I already wrote:
Q: If I change some settings on SLP, will those changes immediately affect old backup jobs (which are not yet duplicated) or they will apply only on new backup jobs?
A: Those settings will be applied to new backup jobs only. Even you do not change a name of SLP and modify the SLP using GUI, you will create a new version of SLP. If you need to apply settings to older jobs, you have to inactivate and modify the SLP using command nbstl. e.g.
-
List of SLP versions.
nbstl -L -all_versions
-
Inactivate a SLP you want to modify.
nbstlutil inactive -lifecycle name_of_SLP
-
Modify the correct version of SLP. Example changing source and destination unit (STUA and STUB).
nbstlutil name_of_SLP -modify_version -version nr -residence STUA,STUB
Q: During duplication, for what job Media server is responsible?
A: E.g. sending data (MSDP, tapes) or controlling OST storage via 3rd plugins.
Q: Is there any way to check duplication job progress and time to finish?
A: Yes, it is necessary to use NetBackup OpsCenter or command line nbstlutil with (repllist or pendimplist or stlilist) option.
Hello Mariusz,
A great explanation as it is. Appreciate you taking time and posting valuble information. however am stuck in a kind of situation.
A few SLPs were modified in the source which had replication as an operation in them. and replication targets are de-commissioned.
now if I have to break the trust to keep the environment clean, I am getting a message, "Trusted master servers are being referred by one or more storage lifecycle policies on the source or target domain(1592).
is there a way that I can identify the replication operation only on the modified SLPs and skip it out on the images?
Thanks,
Kiran
Have you checked versions of SLP? please check it via nbstl -L -all_versions Probably, there are old SLP versions.
Are there any impact of I change the Volume Pools to another volume pools of all the Operations (Operation 1,2&3) of SLP?
