Hi All.
While we're on the topic of backups, I have a question.
Here's a hypothetical configuration:
SystemA 2 x data disks DiskA and DiskB
SystemB 1 x data disk DiskZ
These two machine start life connected to the same network and I use rsync to make DiskA,
DiskB and DiskZ identical.
I then send SystemB to a remote place where there is no Internet access. There is however
a mail service.
I make changes only to DiskA during the work day and wish to have these changes
periodically reflected on DiskZ. Each day I can run a task that sync's DiskA to DiskB.
Is there any way I can capture the changes made to DiskB in such a way that I could put
that information on a CD/DVD and post it to the location of SystemB so that someone could
then apply the same changes to DiskZ?
This could be done using find/tar and some sort of timestamp system but I was wondering if
there could be a more elegant way to do it. Perhaps by capturing something from rsync?
Regards
Brett
