Dear All,
I need to backup a directory with multiple large files of the form
snapshot/ foo-yymmddhhMMSS.log which are snapshots of foo.log.
Conceptually, what I would like to do is for each file
ln -s snapshot/foo-yymmddhhMMSS.log intermediate/foo.log
rdiff-backup intermediate backup
Can anyone suggest a sane way of doing this? I'm mounting snapshot
across a network and I would like to avoid unnecessarily copying
files.
Hello Steve,
I am trying to understand how "ln -s" will offer reduced bandwidth
utilization over something like:
rsync -a snapshot/foo-yymmddhhMMSS.log intermediate/foo.log
rdiff-backup intermediate backup
or
cp snapshot/foo-yymmddhhMMSS.log intermediate/foo.log
rdiff-backup intermediate backup
Either way the data has to cross the network, right?
Also, I can see using a single 'foo.log' to save having to figure out
what the latest log file if you restore, but not for saving disk
space. Assuming each daily log is new and different, rdiff-backup will
just save the whole file each day, just like it would if you copied
over a new file every day and kept them all on hand.
I assume I am just misunderstanding what you are trying to do.
Best,
Chuck
