Two copy solution

[JrAdmin]

Hi,

I am using Netbackup 7(std edn) on windows 2003, i have one Disk Storage unit and one tape drive.

i want my File server backup to go directly on attached disk, then in later part of the day it should go to tape.

1. I dont have Vaulting license.

2. if backup goes directly on tape it takes days since i have 20TB of data.

3. I want to keep disk copy(and tape as well) for faster restore.

please advise how to achieve this.

Thanks

Yes, it can be done. We call it Disk Staging.

See chapter 12 of Administrator's Guide for Windows, I :

but that would clear the images from disk and it will trigger only when the disk reaches its water mark. please advise.

3 other ways spring to mind :

1. Vault (but you need a license)

2. SLP (also needs a license)

3. Manual script that lists the images backed up and then runs a bpduplicate commands to create a 2nd copy.

Hi guys,

I have practically the same question.

I want to backup to disk first and then "destage" these images to tape ASAP for off siting, whilst keeping the initial image on disk for a period of time (Even if just until the space is needed for new backups)

My thoughts on the options :

SLP (Purchasing a license for this isn't something the client will entertain)

Vault Duplication (Image retentions are managed independantly so chance of the disk copy expiring before it has been duplicated to tape)

Basic Disk Staging ?? (Will this meet my requirement? I have read up on this but need some clarification. My understanding is that a Disk staging policy will run as scheduled, say once a day, but it will not expire the initial copy on disk until it needs the space for more images. Is that correct and what dictates which copy you would restore from? ie making the copy on disk the primary?)

Hope you can assist ?

Thanks
