hello,

i have been going around in circles and pretty much grazed all i could find on google and then finally found a way to
get this to work, and though it might be worth communicating this, so it can maybe get included in the wiki ?

i have succesfully installed backuppc under ubuntu and can connect and all is fine.

except, i want my backups on a usb mounted external disk and then could not start the backuppc server anymore
here is what i did:

i followed the instructures here:

http://sourceforge.net/apps/mediawiki/backuppc/index.php?title=Change_archive_directory#Changing_the_storage_location_of_the_BackupPC_pool

i.e.

sudo /etc/init.d/backuppc stop

cp -dpR /var/lib/backuppc/. /mnt/backups1/backuppc
mv /var/lib/backuppc /var/lib/backuppc.orig
ln -s /mnt/backups1/backuppc /var/lib/backuppc

sudo /etc/init.d/backuppc start

and get the famous "can not create test hardlink" error.

the solution after a lot of trying was to

cd /mnt/backups1
sudo su
chmod -R ugo+rwx backupppc

and then finally

sudo /etc/init.d/backuppc start

would work.

i am still lacking a grasp of what the real problem was and what would have been the proper way to go about this.
the permissions of the original installation and the copied installation (which i am using now via soft link) look like this:

original install in /var/lib:

drwxr-x---  7 backuppc backuppc 4096 Feb 13 09:37 .
drwxr-xr-x 63 root     root     4096 Feb 13 10:23 ..
drwxr-x---  2 backuppc backuppc 4096 Feb 13 10:10 cpool
drwxr-x---  2 backuppc backuppc 4096 Feb 13 10:13 log
drwxr-x---  3 backuppc backuppc 4096 Feb 13 10:10 pc
drwxr-x---  2 backuppc backuppc 4096 Jun 30  2011 pool
drwxr-x---  2 backuppc backuppc 4096 Jun 30  2011 trash

after copy to external disk (could not start backuppc server with this, but why. the permissions are all the same):

drwxr-x--- 7 backuppc backuppc 4096 Feb 13 09:37 .
drwxrwxrwx 5 ingo     ingo     4096 Feb 13 10:59 ..
drwxr-x--- 2 backuppc backuppc 4096 Feb 13 10:10 cpool
drwxr-x--- 2 backuppc backuppc 4096 Feb 13 10:13 log
drwxr-x--- 3 backuppc backuppc 4096 Feb 13 10:10 pc
drwxr-x--- 2 backuppc backuppc 4096 Jun 30  2011 pool
drwxr-x--- 2 backuppc backuppc 4096 Jun 30  2011 trash

after chmod (now working)

drwxrwxrwx 7 backuppc backuppc 4096 Feb 13 09:37 .
drwxrwxrwx 4 ingo     ingo     4096 Feb 13 09:44 ..
drwxrwxrwx 2 backuppc backuppc 4096 Feb 13 10:54 cpool
drwxrwxrwx 2 backuppc backuppc 4096 Feb 13 10:54 log
drwxrwxrwx 3 backuppc backuppc 4096 Feb 13 10:54 pc
drwxrwxrwx 2 backuppc backuppc 4096 Jun 30  2011 pool
drwxrwxrwx 2 backuppc backuppc 4096 Jun 30  2011 trash

is it the parent directory permissions that are messing the thing up ?

thanks for any comments

cheers

ingo
