snapshot backup
by Clawson, Simon 25 Apr '01

25 Apr '01

Is it possible to backup just the .snapshot and then perform a restore from this data? I am looking for ways to speed up the backups and this seems to be a possible option. It was suggested to me by a colleague as a method of backing up Clearcase VOBS, but would it be viable for the whole filer. Of course I would need to run a full backup at tleast once a month, but this would help me speed up most of my weekly runs. Any ideas/suggestions/views?

NDMP and network settings
by Scott Mikusko 25 Apr '01

25 Apr '01

Peoples, I recently set up our new NDMP backup system (new ADIC Scalar-1000 tape library, with 2 F760s acting as NDMP hosts with 4 drives attached to each from the unit). Initially I was having trouble getting other filers to backup via the network to the remote drives on the 2 hosts. I was running all my filers on a private 100Mbs Full-Duplex network (utilising the filers' e0 interfaces or quad cards). Funny thing was, I keep seeing really slow and spotty xfer rates and tape writes: small bursts of 65Kb/s then a few seconds of nothing. When I tried backups via dump to local drives, it was 4-6Mb/s, as expected). So, what was causing the painfully slow performance?? On a whim, knowing I had seen something like this before a long time ago with Legato's client pak s/w, I reset the NDMP hosts' ether interfaces to 100Mbs HALF-duplex. As soon as that duplex setting kicked in, my network xfer rates and tape write shot up to the expected 4-6Mb/s rates. Now, I understand that duplex settings can affect network performance, and that in backups I'm essentially streaming data in one direction (which would make half-duplex a sensible option), but as for WHY I needed to set to half-duplex is a mystery. I would think being Full-duplex would be just as well. This duplex issue is, as far as I could tell reading over Netapp and Veritas docs, not address explicity when talking about 3-way backups. While I'm glad I seem to have fixed the problem, the fact that it was a problem puzzles me. So for anyone out there doing 3-way backups or dumps to remote tape drives, had you seen this before? Is anyone running NDMP and remote drives but not using half-duplex network settings? Just curious. -Scott Mikusko

So guys, are you going to start some "inane banter" about the "inane banter"? -----Original Message----- From: Jeff Innis [mailto:figaro911@hotmail.com] Sent: Tuesday, April 24, 2001 17:11 To: toasters(a)mathworks.com Subject: Fwd: Re: OT - swag (fwd) Yes, it's quite interesting the crying about not following protocol when trying to unsubscribe, but not a word from the those same folk about polluting the bandwith with 2 days of inane banter( no doubt someone thinks this chatter was interesting).

ndmpcopy problems
by Leonard, Roger 24 Apr '01

24 Apr '01

i downloaded and compiled ndmpcopy1.2 and am trying to copy a dir from one 740 (blender) to another 740 (grinder). the syntax i use is ndmpcopy blender:/vol/vol1/home/oldlocal grinder:/vol/vol1 -level 0 it prompts me for a password and it looks like it is doing it. the source filer starts an ndmp dump session and the target filer starts an ndmp restore session and i get this output: Connecting to blender. Connecting to grinder. blender: CONNECT: Connection established. grinder: CONNECT: Connection established. blender: LOG: DUMP: blender: LOG: creating "/vol/vol1/../snapshot_for_backup.52" snapshot. blender: LOG: DUMP: blender: LOG: Using subtree dump blender: LOG: DUMP: blender: LOG: Date of this level 0 dump: Tue Apr 24 11:43:11 2001. blender: LOG: DUMP: blender: LOG: Date of last level 0 dump: the epoch. blender: LOG: DUMP: blender: LOG: Dumping /vol/vol1/home/oldlocal/ to NDMP connection blender: LOG: DUMP: blender: LOG: mapping (Pass I)[regular files] blender: LOG: DUMP: blender: LOG: mapping (Pass II)[directories] blender: LOG: DUMP: blender: LOG: estimated 501871 KB. blender: LOG: DUMP: blender: LOG: dumping (Pass III) [directories] grinder: LOG: RESTORE: grinder: LOG: Tue Apr 24 11:41:57 2001: Begin level 0 restore grinder: LOG: RESTORE: grinder: LOG: Tue Apr 24 11:41:58 2001: Reading directories from tape blender: LOG: DUMP: blender: LOG: dumping (Pass IV) [regular files] grinder: LOG: RESTORE: grinder: LOG: Tue Apr 24 11:42:01 2001: Creating files and directories. grinder: LOG: RESTORE: grinder: LOG: Warning: cannot create directory etc: File exists grinder: LOG: RESTORE: grinder: LOG: Tue Apr 24 11:42:16 2001: Writing data to files. grinder: LOG: RESTORE: grinder: LOG: Tue Apr 24 11:45:02 2001: Restoring NT ACLs (if any). blender: LOG: DUMP: blender: LOG: dumping (Pass V) [ACLs] blender: LOG: DUMP: blender: LOG: 502315 KB blender: LOG: DUMP: blender: LOG: DUMP IS DONE blender: LOG: DUMP: blender: LOG: Deleting "/vol/vol1/../snapshot_for_backup.52" snapshot. grinder: HALT: The operation was successful!

The transfer is complete. Elapsed time: 0 hours, 5 minutes, 38 seconds. using df it looks like it copied something to the volume but there is nothing there. i unmounted and remounted and still nothing. what am i missing? also it says it is trying to create etc?? there isn't an etc dir in my source dir. that makes it seem as if it is trying to copy from the root level but it shouldn't be and this is real scary. any help would be appreciated Roger D.

Redundant FCALs with ONTAP 6.1
by Gifford, Josh 24 Apr '01

Hello everyone, I will be upgrading my filer to redundant fcals this week and I wanted to check to see if anyone is already doing this. I don't think there will be any tricks to it, but it never hurts to ask.
