Hi,
I have been using BackupPC to cover about thirty servers
(Unix/Linux/MacOSX/Winxx) and have about 300GB of data on a cycle of fulls
every ninety days and incrementals every twenty four hours. It has been
running well for nearly a year. It is so successful that my boss considers
it a production system, although he is not an open source proponent. Thanks
so much for this!
I see there has been some excellent work done in the beta version on the
tape backup front. I was wondering if those in the know could fill me in a
bit on a couple of things.
I have a ~300GB tape changer, and ATL L200 to be exact, and I have connected
it to the BackupPC and did get it to archive a small system to tape.
However if I tried to use the compression it failed, saying "2004-06-02
16:58:02 Archive failed (Error: /usr/local//bin/BackupPC_tarCreate, compress
or split failed)" None gets me to tape, but I have to be careful not to
exceed one DLT-8000's capacity or I hang things....
I will have to figure this out first, so Question One: How does the "split"
work? Is it a tar of N for each host and then cat'ed into split in the
given size? This would suggest that it gets tmp'd somewhere and spooled out
to tape; From what I can interpret of that code, this seems to be the case.
I have a 500 GB RAID on this box but, well, it is getting full, so I want to
be careful to leave room for the backups...
Question Two: Is there a way of using the -M (--multiple volumes) switch in
tar to accomplish this in the existing code? If it is not too difficult to
do, then it helps me greatly in question three.
Question Three: If the answer to two is yes, then could we also use the tar
switch "--new-volume-script file" ( Run a script at the end of each archive
volume)? This would allow me to automatically have the tape changer move to
the next tape and tar happily continues... I have been using the perl
module juke.pm with the program mtx to do this with some rather kludgy
scripts of my own, but it isn't a prime time solution.
Question four: If the above will work, then might there be a way of setting
this to go on a sensible schedule, with a message to the backup operator
when the Data Storage Elements are full and need to be changed? My boss
wants this in case I get hit by a truck tomorrow on the way to work.
I imagine these things, if they aren't too much trouble to implement could
be included in the main config.pl file somehow.
Forgive my simplistic questions, I don't read perl too well and cant' really
figure it all out on my own.
Thanks in advance,
Dave Scobie
