Re: [BackupPC-users] More thoughts on Laptop backups

Someone recently brought up some questions about securely backing up
laptops with backuppc, and it prompted me to ask about some questions
which I've been pondering.
I'm currently backing up several systems including a laptop which
happens to be running ubuntu linux.
Now one thing I've never properly addressed is that this laptop has
both an internal ethernet card, and a pcmcia wi-fi card. Most times I
use the wireless, but sometimes plug it into the wall instead.
My WinXX laptop is similar. I use the netbios name to identify it
and nmblookup on BackupPC to find it. See $Conf{NmbLookupFindHostCmd}.
So one option is to run nmbd on your linux machine. Or you can modify
$Conf{NmbLookupFindHostCmd} to be any command that returns the IP
address.

Re: [BackupPC-users] web interface problems in 3.0.0
I don't see the difference on permissions.. I see that you don't have BackupPC_Admin in that directory,... and modification time of my index.cgi is a lot older than you's...

[BackupPC-users] Howto backup BackupPC server

Re: [BackupPC-users] Howto backup BackupPC server
I don't think another instance of backuppc would work very well for a number of reasons. However, I think you could do well with copying the raw block device over netcat or ssh. If you are using LVM for the backuppc data you could take a snapshot and not affect regular backups, otherwise you should stop backuppc and unmount the partition first (you are using a dedicated partition, right? ;-) ) Couple tips if you try this: set the readahead on the block dev fairly high before you start dd (blockdev --setra 16384 /dev/device). Then pipe it out with dd and compress it with lzop ( dd if=/dev/device bs=10M | lzop -1c |nc host port). On the receiving end you'd run something like nc -l -p port diskdump. This is what I use for LAN, but for slow links you'd probably want more compression. For good measure you might want to zero out the extra space on the drive before you dump it (dd if=/dev/zero of=blah bs=1M ; rm blah). Of course, this would require quite a bit of disk space and would limit your backup intervals and retention policies... Any other ideas, List? brien Fabio Milano wrote: Hi, How do I backup my BackupPC server? Can I use one BackupPC server to backup another BackupPC server?

[BackupPC-users] Complicated setup with lvm2 snapshot
Hello, I would like backuppc in my complex situation: - I have some real clients and some virtual clients (openvz based) to backup - The virtual linux are on the server (and future backup server) - I use lvm2 I and I would like to use snapshot before backupping to have a consistent backup - I would like to be able to recover from bare metal (Done: I have seen in mailing list that is possible to do semi automatic with knoppix) - I would like to use backup to create a new virtual machine not from scratch but as a clone of other Is it possible? Another question: I have seen that there is a gui from linbox. Are there other gui or enhancements? Thanks in advance for any reply! Mario - Take Surveys. Earn Cash.
