Re: low bandwitdth and big files

Using Adaptive Differencing means that it's not the "whole" file that is
backed up because it has changed, only the changes in the file are backed
up. This mean that if your 1.8GB file is changed with 50MB each day, only
the 50MB is backed up each night.

Adaptive Differencing is an included feature in 4.2 clients. Nothing extra.

However,  what you are backing up is Lotus Notes/Domino databases. I'd
suggest you use the TDP for Lotus Domino to handle the backup instead. The
TDP has incremental teqnique, and is a lot fast than the file backup klient
(when backing up Domino databases).

I have one full backup. What could be the solution? The files change
with minor changes every day but 1.8GB file is backuped up from scratch
every
day.

Burak

Depending on circumstances, this might be a candidate for adaptive
differencing, TSMs version of a block level incremental.  You will still
have to at least once do a complete backup of the big files though.

Hi,
I am trying to backup up big files ~1GB from a low bandwidth line.
Some of the clients fail the schedule very frequently. Could you recommend
me
some options to increase timeout (any kind of timeout). I pasted the
schedlog
of
one of the clients below which starts at 19:00.
Regards
Burak
