Re: BC License ???

The BC license doesn't matter for the type of backup.

You still either need to make a snapshot or snapclone to present to the backup server.


The real question you need to ask is if you need an unlimited BC license... or some capacity based license.

Hi
As Steven said it does not matter what kind of backup etc you wish to do.
To create ANY snapshot, snapclone or mirrorclone on an EVA you NEED a BC licence. You now need to decide if you buy an unlimited or capacity limited licence.

"how can I use BC lisence to get diff backup ?"

Short answer, you can't. The EVA is not a file server, it is a disk server. As such, it has no knowledge of file systems; certainly no knowledge of whether a file is tagged for backup or not.

Snapshot, snapclone, or mirrorclone, the resulting volume is an image of the original at the time of the replication. It's up to the operating system and/or the backup software to determine what files need to be backed up.

Note that if the backup software applies some sort of indicator on files on the replicated volume, those indicators do NOT pass through to the original volume.

Hi Sheldon
If I want to have Diff backup, than I have to get a mirrorclone and then by backup software, I can get diff or inc. backup
and If I get snapclone, then I can get Fullbackup ... because the connection between the snapclone Vdisk and its parent is terminated .
Is it correct ?

Re: BC License ???

No. Your backup software can do anything regardless of snapshot, snapclone, or mirrorclone. All are simply different *methods* of obtaining a COMPLETE point-in-time copy of the original LUN.
Your backup software could perform full, differential, or incremental from any of the three.

No, see my answer posted earlier.
You need a BC licence...

Re: BC License ???

Whats the differences between presenting the original Vdisk to the backup server and using BC license (unless the load on the EVA)?
