Incredible-Inline Backup

[V_Dinesh]

HI everyone,

I am going to share my gladdest experience about the Inline technology which is provided by NETBACKUP. The term inline referred as multiple. With the help of this technology we can run multiple copies of a backup with different definitions. I am not very sure about the other backup technologies since I have been working with NetBackup for the past 2 years; it’s really amazing experience that the NetBackup has lot of advanced technologies, one of them is INLINE Backup.

Technically what inline copy will do is, it will write a single backup in to multiple tapes or multiple disk destinations which will rapidly reduce the time window by not initiating the backup copies one-by one.
For example if we need 3 backup copies for a single server, what we will normally do is, will initiate the fist copy. After that we will initiate the second copy once the first copy get completes and then the final copy.

With the help of this inline technology we can run all the 3 copies simultaneously without impacting the server (which is being backed up) performance

Please refer the attached document to view the pictorial representation.

Yip, pretty good technology.

Another good thing to note is that you can write inline copies to multiple media types at the same time e.g. LTO3, LTO4 and disk and NetBackup will pause all the backups if it needs to change e.g. the LTO3 tape.

We actually have LTO3 media and LTO4 media configured as the same media type.  Both these media type are being written to and read from LTO4 drives.  Some of our inline copy backups are configured to write OFFSITE copies to the LTO3 media (in the LTO4 drive) and the ONSITE copy to the LTO4 media and it all works sweet.

When I did my tests with inline copying in our environment and to the same media type, it took around 15% longer than a normal backup directed to a single tape.  This is way faster than using 2 or three times the amount of time when doing each copy in a serial fashion.

Thanks for Sharing your Experience :)

SLP is more powerful and evolved technology available.

1) create as much has copies you want different targets , different retention levels
2) Backup to disk and duplicate to tape ( temporary disk staging ) but more powerful.
3) automatic aging for disk based backups. Duplicate backup image for long retention to tape automatically.
4) network optimized duplication choose the best server for duplication job
5) hierarchical duplication , duplicate from copy n doesn't required first copy
6) if you multiple backup targets ( something like inline ) if only one copy is successful rest will be duplicated automatically.
7) Set job priority for duplication jobs
8) data classification 
Try this one.... you wont regret it

Much more ..

 Hi Krishnan,

    Could you please explain about the term SLP and how to use it.....

Thanks in advance

SLP stands for Storage Lifecycle Policy.
