Backuping up CIFS Shares

Hello,

  We brought a new FAS-2240 online starting in December and I have been working to move it into production and so far so good.  I have FC LUNs and CIFS Shares up and running in a test production environment and it is working as advertised.  The next hurdle is backups.  I have been reading over come of the posts here and it seems that unless we use NDMP to backup data the only other option would be to present the CIFS Shares as iSCSI LUNs as well to the backup server as new disks and conduct backups that way.

  Are there any issues with presenting active CIFS shares as iSCSI LUNS as well?  In most situation all iSCSI activity will take place after roduction hours and it is just being used to copy data for backups purposes.

TIA

Jim

Re: Backuping up CIFS Shares

There is no way to present CIFS shares as iSCSI LUN. Snapshots provide quite efficient backup for file shares.

Re: Backuping up CIFS Shares

  I have a requirement to tape out everyday so I need to backup these shares.  Is there another way besides using NDMP?

TIA,

Jim

Re: Backuping up CIFS Shares

The only other way is to map share and backup it from client. Also, for NDMP you do not always need tape, attached to filer. Most backup software I know supports three way NDMP backup, when data stream is sent to media server (tape server) via LAN.

Re: Backuping up CIFS Shares

Hello Jim,

You might find the following post useful regarding different NDMP backup options:

FAS2220+ Entry Level FAS backup to Tape - Connectivity options (SAS and NDMP) (https://communities.netapp.com/thread/25746)

I hope this is of some use.

Adrian

p.s. CIFS/NFS is file level, iSCSI/FC is block level, the flexvolumes have different properties set for very different reasons. NetApp has great features for providing more efficiency backups using the snapshots & snapvault for D2D backups and then it will allow you to backup to tape more effectively so you don't have to backup to tape in-efficiently on a daily base.

Adrian,

  I cannot seem to follow the link.  I asks me to register...um I already thought I did that which is why I am here.  Can you give me the quick down and dirty please.

TIA,

Jim

Re: Backuping up CIFS Shares

Indeed you should be able to access it as its part of the same community. Please see the attachment. It's not official documentation but hopefully it helps.

Heres the link again, just in case https://communities.netapp.com/thread/25746 you may have to login again!?

Let me know your thoughts on the doc.

Adrian,

  Woo Hoo it works.  Thanks for all your help.  I added our FAS-2240 as a NDMp Device in Backup Exec and am running a test backup now.  Kind of slow, 600MB/min, but it is working.

Thanks,

Jim

Re: Backuping up CIFS Shares

Excellent just out of curiosity what set up did you use? from what you stated above I'm guessing it ethernet connected to your backup exec server and therefore I'd probably say 600MB from a 1gb port isn't too bad although you have raised a very interesting topic which I wouldn't mind understand more on.... Backup transfer rates

if directly connected via FC then I would expect up to the 1, 2 or 4gb throughput. If its going over the ethernet via the ndmp server then your initially capped at the 1gb port HOWEVER this may lead on to discussing whether you can have VIF's / IFgroups which can help increase that throughput, if not for throughput then for resiliency.

You may want to try a few different options. Maybe having a NetApp VIF/IFGroup set to either multiple mode or LACP mode (depending on whether your switch or server support this) this will then give you two bonded ports however you will only initially have 1 IP address assigned across the two ports and therefore you are still only capped at 1gb speed for each session (IP pairing session) connectivity. You can then add an additional IP alias to this VIF/IFGroup which should then allow an additional 1gb session which should then increase the throughput (ideally). This would also depend on the sessions transfering and whether its just one large session. you then also have to ensure the server is also exceeding the 1gb throughput capacity if its connecting to a switch and then from the server to the Tape device.

What connectivity do you have from your server to your tape device (FC or SCSI or other)?

Thanks in advance,

Adrian

Re: Backuping up CIFS Shares

Adrian,

  Currently backup exec is running on a HP DL-380G5 with two HP NICs Teamed.  The tape unit  is a MSL-6000 with dual drives connected via SCSI.  Currently our biggest jobs come from a NAS Cluster and I average about 1200MB/min out of them with single NICs.  They do however have the BE Agent installed so there is probably some good compression.

  I will let this test run and see how it goes.  If I cannot get the performance I need I will creat a new VIF using two NICs and see what performance I can get out of that.  I wil probably start with multiple mode and if that does not get any better performance I will go to LACP.  Having performed some initial test with both modes I seem to get better performance out of multiple mode so far.
