RE: need help with Legato and Filer backup
by Benn, Paul 19 Dec '00

19 Dec '00

If you have files with NT-style permissions, though, backing up over NFS is not a desirable option as you will loose any NTFS file attributes including ACLs and DOS attributes. Backing up over CIFS not only retains NTFS file permissions but it retains UNIX permissions as well as tracks an archive bit on UNIX files (so NT apps can do "incremental" backups). If you have a lot of data, you should really consider an NDMP based solution. You can read more on NT based backup here: http://www.netapp.com/tech_library/3052.html Regards, Paul Benn Network Appliance -----Original Message----- From: Michael Salmon [mailto:michael.salmon@uab.ericsson.se] Sent: Tuesday, December 19, 2000 3:13 AM To: Dell, Mary; toasters(a)mathworks.com Subject: Re: need help with Legato and Filer backup +-- On Friday, December 15, 2000 11:28:24 -0600 "Dell, Mary" <mdell(a)mesirow.com> wrote: | | Is anyone out there using legato to back up your filer?

2 questions for f760
by neil lehrer 19 Dec '00

19 Dec '00

hi, 1. we will be moving our home and share dirs from old sun boxes to f760. the home dirs on the suns were set up like: \home \home\a \home\a\abe \home\a\allen \home\b etc. in other words, user homedirs under the first letter of the id. i was told this was done for performance reasons, inode searching, on the sun boxes. do i need to use this structure on the 760? is there a similar issue on filers? or can it just be \home\userid? 2. i have heard i can connect a tape device to a fibre channel card rather than the scsi to get better performance. anybody know anything about this? i'm not looking for a separate network, just more performance. current config is: 2 atm cards fcal card cluster card [i am configured with 1 f760 as active and the other as standby, do nothing. the tape drive will be attached to the active filer]. plus the other normal cards. thanks.

Given there are no single tape devices that will likely top the maximum throughput available on a fast-wide parallel SCSI connection, moving to FC won't buy you much. If you say wanted to go from two devices to four, then, yes FC might be a suitable move. I'm not aware yet of (m)any tape devices that do FC natively - most currently require the use of a FC-parallel-SCSI 'bridge' (they're SCSI routers to afficionados). > cluster card [i am configured with 1 f760 as active and the other as > standby, do nothing. the tape drive will be attached to the active > filer]. Then the costs and difficulties in using FC tape hardware outweigh the benefits. >-- End of excerpt from neil lehrer -- -Mark ... an Englishman in London ...

FW: Backups Using Netapp Dump
by Daniel Oxenhandler 19 Dec '00

19 Dec '00

Jim, We are very happily using Ontap's dump program. We have a DLT7000 autoloader connected to a Solaris box, and use commands like this to back the filer up over a dedicated 100Mbps net: rsh filer dump 0ubf 63 rmt@solaris-box:/dev/rmt/1ubn /vol/vol0/projects It's been totally solid, and captures both CIFS and UNIX metadata, which is a requirement for us. This solution works well if you don't have too many filers, or too much data (we have 1 filer and <200GB). We abandonned paid for Legato licenses to implement this solution, BTW. To me, a commercial solution would start to make sense if your numbers were significantly larger, or you wanted to take advantage of the NDMP protocol, or some of the more advanced libraries, etc. that are out there. Otherwise, dump rocks!

We're currently backing the filer up over NFS from a Unix host. Works fine, basically, but it stresses the network a bit. (100 Mbps full duplex) In the near future we're probably moving to Networker 6.0, which can back the filer up directly via NDMP, and we'll possibly set up a dedicated net between the backup server and the filer for the backups. -- Leif Nixon Sysadm/developer Ericsson SoftLab AB ---------------------------------------------------------- E-mail: nixon(a)softlab.ericsson.se Phone: +46 13 23 57 61 ----------------------------------------------------------

need help with Legato and Filer backup
by Dell, Mary 19 Dec '00

19 Dec '00

Is anyone out there using legato to back up your filer? We just got our filer running and are not able to get legato working for it yet despite help from support and so on. We've got the client installed on the filer, we've created a client & group setup for it on the (unix) networker server, and we've got the (eval) enabler--but it keeps failing. Any ideas or suggestions would be a big help. Thanks, Mary Dell

about blocking factor
by Abu Ihsan 19 Dec '00

hi, i would like to know how to find the blocking factor of a volume and what is the default size and can we modify them as we do with our unix box (newfs). i know we can increase the inode on the fly (very cool). tq, --fared __________________________________________________ Do You Yahoo!?

RE: DLT8000

Mike, the DLT8000 is not supported in native mode until DataOnTap version 6.0. You will have to use the /etc/cloned_tapes file and add an entry that says: QUANTUM DLT8000 EMULATES QUANTUM DLT7000 Please be aware that this means you will only be able to get DLT7000 capacity on your 8000 drive. On our NOW web site at the following URL you can see all of the supported drives and the DataONTAP versions at which they are supported. http://now.netapp.com/NOW/knowledge/docs/olio/cert_matrices/tape_drives.shtm l -----Original Message----- From: Mike Horwath [mailto:drechsau@tiny.net] Sent: Friday, December 15, 2000 3:08 PM To: toasters(a)mathworks.com Subject: DLT8000 I have a NetApp F760 and I want to use a DLT8000 on it.
