Hi,

We have primary site for disk backups, and a secondary site for DR.  We want to backup to USB or another site so we can take it off-line for security reasons.  What's the best way to achieve this?

Total DAta: 7TB

Scenario 1:

2 12 TB USB/NAS drives directly attached to the media agent

1.  Perform a full on USB 1 and USB 2.

2.  Every odd month, plug in array 1 and sync it up to the backup.

2. Every even month, plug in array 2 and sync it up to the backup.

Question, after the initial full, will I be able to do an AUX/DASH copy to the USB drive? I don't want it to take 36 hours on USB2 speeds for each monthly offline copy.

Scenario 2:

Use a third site/SAn to host a third copy and perform weekly or monthly Aux/DAsh copies.  The idea is to take it off-line, so we may need to create 2 disk libraries in this remote location.

1.  perform a full to library 1 (let's assume this is 5*4 TB hard drives in the SAN).  Remove disks

2. Perform a full to library 2 (Same as above)

Each month (or set time), physically remove one set of disks and put them aside, while the backups happen on the other set.  Prior to removal confirm data is on the disks?

Question, would it cause problems to plug those disks in and will I be able to do an AUx/DASh copy and it'll only copy changed blocks to the library? Be it library 1 or 2?

Hi light, could you clarify, where will the USB be attached?  Could you share also how how the copies are currently setup, Primary & how many secondary copies also if they write to disk or tape?

Also to confirm Simpana version and service pack?

Latest simpana, sp 9.

I have not setup anything yet, and the USB wil be connected to the media agent directly.

Hello light1,

Pls see if the below helps.. indeed backup to USB by using a PnP library.

Check these out for info related to aux/dash to a remote datacenter.

So as I understand it, seeding is for first time across the WAN, and then replication afterwards?  And you are saying I can use the same process for off-line backups?  I will already be replicating across the WAN...i may or may not seed depending on the bandwdith, we'll see.

Could you clarify what you mean by "off-line" backups?

backups so that an attacker can not access them online...once every 2 weeks, and swap those disks

Any help is appreciated.

I want to backup to Primary, DR, and 2 secondary off-line copies, rotating the final 2, and this can be done via USB or via 100Mbps link.
