Subject: subtree backups

Hi,
=20
Legato's nsr_client or uasm page or one of those says that you can't use = a 
"*" in the saveset name, which makes this much more difficult. (It = appears 
that it works, but when you go to restore a saveset, you have to = specify 
paths, and it is unsupported, so it is possible that going = forward it may 
simply not work).
=20
This leaves you with the client-side script idea, and hard coding the = subtree 
paths.
=20
Hard coding is much easier, both in implementation and in maintenance, = than a 
client-side script that replaces save.exe.=20 You could set your saveset as:
x:\projects\path1
x:\projects\path2
x:\projects\path3
=20
This will get you three streams, working around both tape limitations = 
(depending on your specific config, of course), although this requires = that 
your projects be broken up intelligently. If the problems is that = you have 
lots of small files, this will also get around the kernel = limitations on 
doing NTFS file/directory lookups, although give your = size, I'm suspecting 
your average file size isn't the issue.
=20
One theme that we've seen a lot of recently is that when you have a = partition 
that large, and backups become an issue, it gives you and = opportunity to step 
back and look at your policies for sizing of = partitions. If you include 
backup requirements as well as technical = limitations of partition sizing, you 
may decide to look at your internal = best practices.
=20
If you've ever done a chkdsk of a 1TB+ NTFS file system on Windows, = you'll 
know what I'm speaking of. (Unless you are using a different file = system, 
like VxFx, that is).=20 =20 You may also want to consider using Windows mount 
points that are at a = subtree level--x:\projects is one partition, 
x:\projects2 is another, = etc. Having large partitions is inherently a risk, 
even with NTFS5's = journaling--if you ever have to do a boot time checkdsk on 
that drive, = you are in for hours of delay in booting. If you have several 
partitions = under the x: drive, NetWorker will inherently create multiple save 
= streams for them.
=20
BTW, we've done the client-side script, and it is more difficult than = you 
would think. Lots of details to understand, and unless you = understand the 
subtle NetWorker issues (automatic directive creation, = automatic mount point 
generation, root partition backups, etc), you may = find that it is a 
maintenance headache, and misses important data to = boot.
=20
So I guess I have one question--is your directory structure condusive to = 
simply hard-coding the saveset to something simple, or do you have a = 
particularly wide or deep directory structure that doesn't work with = this?

Andrew,

If I understand correctly you want to create a script that lets you backup a 
subtree in 3 parts separate from the normal backup of that volume e.g.

master_volume =3D X:\
Subtree =3D X:\all_data\bigdata

and you want to split the Subtree into 3 parts e.g.

Subtree_1 =3D X:\all_data\bigdata\[a-k]*
Subtree_2 =3D X:\all_data\bigdata\[l-s]*
Subtree_3 =3D X:\all_data\bigdata\[[t-z]*

So now you have in total 4 subtrees on this volume

You allso expect to run Subtree_1 to 3 at the same time and so expect a faster 
backup.

Subject: ALL saveset problems

Hi all,

 

I am running a Windows 2000 SP4 server backup with saveset - ALL.

 

It is able to properly backup all partitions, SYSTEM files, db etc. but does 
not backup F:. The Networker server stops responding or writing data until you 
abort the group. F: is a local NTFS partition.

 

However, if a backup using saveset - C:\,d:\,e:\,f:\, if backs up f: as well.

 

Could anyone help me with this?

 

Regards,

Anuj Mediratta

Hello,

You have to disable the VSS feature for the client.
In nwadmin GUI, you have a field called 'Save options', enter VSS:*=off.
