Levi..you mean to say during backup of a client NW updates the CFI on the
backup servers disk however it writes the entire the CFI for all the backups
of that client within the browse policy to tape. Am I correct?
index path for all of the clients is the same. Index information written to
tape, is in GB's and not in MB's for many clients(of course for some of the
clients it is in MBs). Total index information of all clients written to
tape is in GB's.
Thanks,
Srinivas Rao.

It uses 180-200 bytes for each file regardless what the size of the file is.
The total index size on disk and tape should be the same. The way it backs
it up during full backup is as follows: During backup of a client it updates
the CFI on the backup servers disk (index path), and when backup of a client
is finished it backs up the CFI (with the backup server as the owner of that
saveset).
To check the different CFI savesets size you have to look at the backup
servers savesets, you can do it with Networker user (saveset recover) on the
backup server or mminfo.
May be you have used another index path on most of the clients?
Check the clients setup in nwadmin (index path).
Or may be you have observed in MB to tape?
Best regards,
Levi

Thanks Levi. You have mentioned that NW uses about 180-200 bytes for each
file it backs up. Does this depend on file size? What are the index sizes,
if file sizes are 1KB, 10MB, 100MB or 1GB? Is index size same for all these
files?
Could you please tell me how NW writes index information in tape and in
server(C:\ProgramFiels\Legato\nsr\index). I have seen during weekend backup
total clients index size, to be written to tape, is around 40-50GB whereas
CFI occupies around just 3GB disk space in my server.
Thanks,
Srinivas Rao.

Hi Srinivas.
It depends on the number of files on a give Networker client, not disk size.
And of course the browse policy and how often full backup runs.
I think it uses about 180-200 bytes for each file it backs up.
So, in your case, with full every weekend and browse policy 6 months,
you have to find the number of files on a given server and multiply it with
26 (26 weeks in 6 month) plus aproxemately 10 % incremental in 26 weeks, and
multiply this with 200 bytes each.
Best regards,
Levi

Dear All,
I have a Networker6.1.4 on Windows2000 Server, with 6 months
browse/retention policy, backs-up around 60 NW clients. I have seen for many
of the clients index size is in GBs(around 2/3/4GB) during weekend full
backup(of around 3.5TB). During weekend backup total index size of all
clients to be written to tape is around 40-50GB. However it occupies only
3GB space in my server to store all these CFI during weekend backup. Can
anyone tell me how Networker store Client File Indexes on a server and how
it calculates index size?
Thanks,
Srinivas Rao.
