massive drop in performance after upgrade from 3.1.20 to 3.3.02

Hi,

I've recently upgraded an old debian lenny server, where backuppc was
nicely and quietly doing backups in a "reasonable" amount of time.

I terms of time, a full backup of *localhost* took about 6 hours.

Now, after upgrading the box to the latest stable debian release and,
coming with that, backuppc 3.3.02, the backup of localhost now takes
more than 10 hours.

Incremental backups are not very different, even they now take a little
less than 10 hours.

The backup itself is about 180GB in size, so by any means 10 hours is
just weird.

I understand, that the new backuppc version is not the only factor in
this equation, but maybe someone of you has any clue about what goes
wrong here.

Thanks in advance

Udo

How to Exclude?

Hi all,

I am running into another issue with my new backuppc system. I will
backup the backuppc system itself. Please don't discuss if this it
helpful or not- I will use it to restore older configuration files.
Obviously I have to exclude /var/lib/BackupPC so I tried with excludes
in the BackupPC/pc/host.pl:

$Conf{RsyncShareName} = [
  '/',
  '/boot'
];
$Conf{BackupFilesExclude} = {
  '/var/lib/BackupPC/' => [
    '*'
  ],
  'var/lib/BackupPC/' => [
    '*'
  ],
  'var/lib/BackupPC ' => [
    '*'
  ]
};

None of these three is working. Every time when I start a backup it
travels through the /var/lib/BackupPC directory. and backs up cpool and
so on.

What am I doing wrong?

Problem - resolve host name with 2 different ip's lan/wifi

Hello i got a problem with backuppc.

I got domain controller which is DNS server aswell. When i added host "Somehost" and user for him that i
earlier created in AD backuppc and i want to start full backuppc for this user i got an error no ping.

I loged in to AD, went to DNS and i got there same user with 2 different ip's. f.e  somehost 10.0.0.1(lan)  and
somehost 20.0.0.1 (wifi).

when host is connected via lan and i delete from DNS somehost 20.0.0.1 then it's working fine, but without
doing that i'm getting no ping.

Next i checked when i got in DNS 2 different ip's for somehost i loged in to backuppc via ssh and tried to ping somehost.domain

first try no response,
second try it responded from lan,
third try no response,
fourth try it responded from lan.

Can i force backuppc for using only lan ip's ? Or do something that backuppc will check both elements from DNS  [Question]

rsync out of memory

Hi,

I decided to implement BackupPC at a second location as it is really
reliable and nearly perfect! ;)

Unfortunately, I'm getting errors when backing up one host. My debugging
gave the following results:

Dump Databases

Hi:

I databases postgres and mysql to back and I wonder if is it possible to add two script DumpPreUSerCmd?, eg
DumpPreUSerCmd $sshPath -q -x -l root $host /usr/local/sbin/automysqlbackup.sh; $sshPath -q -x -l root $host /usr/local/sbin/autopgsqlbackup.sh

Re: PIPE error

Hi All,
I've resolved all my backup issues but 1.
A backup will start on this server and then end prematurely with the following:

Not saving this as a partial backup since it has fewer files than the prior one (got 2335 and 0 files versus 2335)

I was able to get the server connected and backing up.
In the 'ClientNameAlias' field, I entered the servers IP address.
Although the other change I still need to make is to reapply Windows firewall and see if it's still good.

yes, sorry. I was thinking about DNS and missed the netbios case. I added that after checking the code to make sure the message actually means what it says and failed to realize the implication.

Current status

Hi,
for a new installation is v3.3.0 (getting somewhat oldish) still the version of choice?
Is there anything new in the pipeline? (i.e.: should I wait a bit?)
In general: is there some new about 4.0.0 timeline?
TiA
Mauro

BackupPC backup speed is about 60Mbps ... slow?

PC network interface: 1000Mbps with Cat6 cable
backup server network interface: 1000Mbps with Cat6 cable
router: 1000Mbps (put through about 700Mbps)

CentOS 6.4
BackupPC latest version
10TB data from PC backup to backup server by SMB (shared from windows)

When the full backup start:
the average is about 170Mbps (iftop)
after 24 hours ... still processing ...
the average is about 60Mbps (iftop)

Yes. file size and numbers matter
the data included GB videos and millions of small files

Is it normal speed or below average?

thx

error disk too full, deleted pc, how to delete cpool?

finally SOLVED ....

1) delete the backup LVM
2) rebuilt all hdd to a new LVM, mount it on /backup
3) unlink & delete /var/lib/BackupPC
4) symlink the /var/lib/BackupPC to  /backup
5) chown -R backuppc:backuppc for both
6) mkdir /backup/pc /backuppc/cpool
7) restart backuppc!

it works without reinstall backupPC

ssh-keygen on Ubuntu 14.04

Hi all

on an Ubuntu 14.04 server I've installed backuppc afresh, moved 
/var/lib/backuppc to /mnt/raid (a raid1 soft raid setup) and am in the 
process of configuring the last steps.

Web access is fine and I can add hosts etc but I've reached a stumbling 
block with the ssh-key setup. Following the backuppc install notes on 
the site I do:

su - backuppc

and would then expect to follow the prompts after doing ssh-keygen 
(which I've done successfully on another box, albeit on 12.04). However, 
I hit a snag with this:

No directory, logging in with HOME=/

Permissions are such that backuppc cannot create a home directory for 
itself. So when I try and run ssh-keygen I get permission error if I try 
and save to default location from the command.

Enter file in which to save the key (/home/backuppc/.ssh/id_rsa):
Could not create directory '/home/backuppc/.ssh': No such file or directory
Enter passphrase (empty for no passphrase):

I've therefore tried to save to /var/lib/backuppc/.ssh/id_rsa as I know 
backuppc is the owner of /var/lib/backuppc.... but get this error:

open /var/lib/backuppc/.ssh/id_rsa failed: No such file or directory.

So I took the plunge and created /var/lib/backuppc/.ssh/ and created the 
public key there.

And then run ssh-keygen -t rsa which completes with no error and an ls 
/var/lib/backuppc/.ssh/ shows the 2 files id_rsa an id.rsa.pub there

If it then try and copy the file from backuppc to my target client with

$ ssh-copy-id -i /var/lib/backuppc/.ssh/id_rsa.pub root <at> remoteserver

I get this (this is sending to a Mac 10.5 server in case thats relevant)

mktemp: failed to create file via template 
‘//.ssh/ssh-copy-id_id.XXXXXXXXXX’: No such file or directory
mktemp failed

I suspect I'm making this more complicated and difficult than it really 
needs to be. And perhaps a simple tweak right at the outset to sort my 
lack of home directory on backuppc user or similar may be the solution. 
Or perhaps I need to enable root on the server?

I've been banging my head against this metaphorical wall for some time 
now so anyone who has any suggestions please let me know.

best.
