I run amanda in parallel to backuppc. I set it up long ago and it
is almost as trouble-free as long as you remember to swap tapes.
It is more trouble to restore, so I only keep the tapes as an
off-site emergency copy and haven't had to use them for restores
since setting up backuppc.

I still consider it experimental, but I have a system working
with an internal 250 IDE drive configured as a Linux software
raid mirror with an external firewire drive and have been
swapping the external drive weekly for offsite storage. It is
somewhat awkward because Linux won't auto-detect the drive and
it takes several manual commands to bring it up, but it will
re-sync in about 8 hours and you can continue using the system
during that time. I've also seen some nice cages to hot-swap
SATA drives that should work as well, although one nice feature
of my external case is that it also has a USB connector and
could be connected to a laptop running Linux to grab a file
from the offsite copy without extra controllers.

The problem only shows up when you have hundreds of thousands of hard
links. There is no efficient way to track them, so the copying software
must build a table mapping names to inodes and search it for every file
with more than one link. Since it is rare to have more than a few
hard links on a filesystem, most programs don't do anything to optimize
this operation and it might take several days to copy a 100 gig backuppc
partition - in fact I gave up after 3 days and let my 250 gig drives
start from scratch.

cygwin rsyncd on windows 2000

Hi, I'm having a horrible time getting cygwin rsync to work on a windows 2000 box. First, I can install it as a service but it won't start. I install the service with the command: cygrunsrv -I "rsyncd" -e CYGWIN=nontsec -p /bin/rsync.exe -a '--config=/etc/rsyncd.conf --daemon --no-detach' When I try to start it, I get the helpful message: "Could not start the rsyncd service on Local Computer. Error 1067: the process terminated unexpectedly". I've opened up the windows permissions as much as I can on all of the files in the cygwin /bin directory as well as on the rsyncd.conf and rsyncd.secrets files and the rsync log, pid and lock files. I've also tried running the service as both the system user and as a local user account. Is there any way to debug why this fails to start? I can start the rsync daemon from a command prompt, and I can connect to it and get a list of shares. But when I try to transfer files I get the message: @ERROR: auth failed on module test rsync: connection unexpectedly closed (0 bytes received so far) [receiver] rsync error: error in rsync protocol data stream (code 12) at io.c(359) I have strict modes = false in my rsyncd.conf, and I'm sure the password is correct. I've got rsyncd working between linux boxes so I'm not completely clueless about how to set this up. I blame windows :) I suspect it's a windows permission problem, which is always a PITA, at least for me. FWIW, here's my rsyncd.conf: use chroot = false max connections = 2 log file = D:/cygwin/var/log/rsyncd.log pid file = D:/cygwin/var/run/rsyncd.pid lock file = D:/cygwin/var/run/rsyncd.lock secrets file = D:/cygwin/etc/rsyncd.secrets strict modes = false [test] path = d:/tmp/test comment = test auth users = backup read only = false list = true I'm using cygwin-rsyncd-2.6.2_0 with a full cygwin install (only 1 cygwin1.dll) on the windows side. The unix side is using rsync rsync-2.6.3pre1 on Solaris 2.8.

Archive failure

I just setup the backuppc machine as an archive host and tried to archive the existing backup. When I tell it to archive, I receive the following error: Software error: Insecure dependency in require while running setuid at /backuppc/lib/BackupPC/Lib.pm line 348. For help, please send mail to the webmaster (root@localhost), giving this error message and the time and date of the error. --------------------------------------------------------------- Any suggestions? Also, is there a way to automate the archive process so it will automatically archive the existing backups every night or whatever. Thanks.

BackupPC and Arkeia Light

Hi, We're running BackupPC (Version 2.1.0, released 20 Jun 2004) and Arkeia Light 5.2.20-1 on our Linux server. We use Arkeia to backup our backuppc directory on tape. The problem we have is that the backups on tape take much more space than on disk. I've seen the discussion on the list about other backup applications having problems with BackupPC's hard links. But Arkeia claims to handle hard links and we have not been able to manually recreate the problem. I wonder if there is anyone out there that have experience running BackupPC and Arkeia in this kind of configuration? Has anyone used another free tape backup-system, for instance Amanda, that works well with BackupPC? (Unfortunately the new archive feature in BackupPC does not help us since we want to backup the whole BackupPC configuration and data.) When we tried to manually recreate the problem we created a file with a couple of hardlinks to it. In that case Arkeia only saved one copy of the file. Is this example not sufficient to simulate BackupPC's usage of hard links?
