Duplication by SLPs - Does the duplication occur for partially complete jobs (status 1)?

[daniel_sung]

Hello,

I was wondering whether the Storage Lifecycle Policy submits the duplication job to be performed if the backup job is partially complete with a status 1 or only on status 0. I would be very grateful if anyone could let me know how SLPs select which jobs are duplicated and which are not, as I am looking at some data loss and would like to know if this is a possible cause. Thank you.

Regards,

Daniel

Hi,

     Even when is partial backup this will create a successful image and if your policy was setup to use an SLP the new image will be under the nbstserv list, you can easy know this checking the image with:

bpimagelist -backupid <image> -L

     The output you will see is copy 1 and the SLP but also the status of the image if is in progress or completed, another way to check this is with:

nbstlutil list -U -backupid <image>

Check it out, but Im sure you are good.

Regards.

That's good to hear. It's just that I have quite a few jobs that are in my catalog but they didn't appear with nbstlutil stlilist -U and now I believe all of the data for those jobs is lost, but at least I know it isn't due to this. I will have to find some other cause. Thanks.

If your at 6.5.4 or less there are a lot of bugs out there that can cause data loss, try to upgrade your NBU master the highiest you can, like if you modify your SLP through the GUI and you are at version 6.5.4 this will disconnect your images from your SLP duplication retention and all images under this SLP will expire on their first copy time, must be very carefull on this, if you are at 6.5.5 when you modify an SLP it will create a new version of the SLP and all the old images will remain on version 1 and the new ones on version 0.

To know if you have multiple SLP version just run:

nbstl [storage_lifecycle_name]  -L -all_versions

Is probable that if you are under a highier version than 6.5.5 your images are under a different SLP version.

Hope this helps.

Regards.
