tar size problem
Nick S
I have come to this thread by way of another problem that I have
encountered.
Firstly, as you will see in the script that I have quoted in this
message, I was wanting to create a set of gzipped tar archives for a
series of directories all under a couple of trees.
My dilemma was first finding out that tar doesn't like anything over
2GB that isn't a streamed device such as a tape store. I have two hard
drives installed in the network server, and hda6 holds all the data
that I want to automatically backup.
The idea is that this script will take everything on hda6 and create
the archives on hdb6 neat 'n' tidy, retaining a very similar directory
structure. I then copy ala 'Samba' all this to a windoze workstation
to be burnt off on DVD's <nice>, which are then taken off site <sain>.
We have a couple of MAC's on the network and numerous erroneous files
with filenames that have been munged, and I can't seem to be able to
create a folder named 'con' for some dumb ass microshit reason. So
packed archives it has to be, otherwise I have to manually drive the
copy process, which is such a 'soft killer', stop/start/stop/......
arrghhhh
* Secondly, upon further contemplation, is this the best way to go
about it? Thoughts?
