Help before giving up on BackupPC

Hello all,

 

I am using a pretty vanilla installation of BackupPC and love the simplicity and fact that it just works as it’s supposed to.

 

My problem arises when trying to back up windows clients over rsyncd.

 

I have 3 win boxes, all running Win7 and the rsncd server. Functionally, they perform fine. I’m able to backup, restore, etc. My initial tests were with small folders and not the entire drive.

 

HOWEVER… each win box has somewhere between 20GB and 3TB of data, and despite being on wired gigabit Ethernet, the 3TB machine ran for over 8 days and still wasn’t done before I pulled the plug and called it quits. Backing up 3TB over gig-e should be able to be accomplished in under 1 day, so I’m at a loss of what to do next.

 

Is rsync “really” that slow? Am I doing something wrong? Is it limited to just the windows client? When I was evaluating Bacula, I was able to do the same backup in 1/10th the time (or at least it felt that way since I don’t have hard numbers).

 

Before giving up on BackupPC and considering an alternative, can someone give me some advice?

 

If it helps, the server is beefy, quad-core i5 proc w/ 4gb ram and 6TB raid5.

 

Thanks,

 

Marco

Errors on backup

I can’t figure this one out.  It doesn’t provide much information, but of course I am not sure what I am looking for.

 

These are the lines from when it aborts:

 

tarExtract: Done: 0 errors, 38 filesExist, 25058590 sizeExist, 24507089 sizeExistComp, 364 filesTotal, 466311750 sizeTotal

Backup aborted ()

 

 

I am not sure what all to post for you to help, as I am new to this.

 

 

 

 

 

 

 

Thanks,

Dan

Problem during zipCreate

Hi, I'm using backuppc                            3.2.1-4  (official Debian 7.5 
package)

I need to restore a huge directory (about 8 GB) through web interface but I've 
problem with browser (timeout).
So, I'm trying to use CLI, with this options (as backuppc user)

/usr/share/backuppc/bin/BackupPC_zipCreate -h someserver -n 41 -c 0 -s home 
account/public_html > /tmp/backup-server.zip

I noticed that zip file is still empty after several minutes..
This is the output of strace:

Mail missed backup only after 30 days

Hi,

we're using backuppc for several Linux machines. If a server is unavailable we get a message that the backup failed which is perfect. But for one server we got the message only when the backup failed for 30 days so we where not aware of the problem, but after 30 days. I've tried to find any info on how this can happened, but so far I've found almost no info on how to debug this problem or on which mail is sent when. Another server which is unavailable regularly does trigger the mails and all other messages seem to be sent.

Anybody knows where to start debugging this problem?

Met vriendelijke groet,

Micha Kersloot

BackupPC 4.0.0 - can we now store files to any filesystem?

Hi

As version 4 doesn't user hardlinks, can I use any filesystem to store data?

I would like to use remote hardware NAS to store data. This is a simple, cheap NAS for smal office usage and it provides SMB connectin so i was going to mount it to my filesystem and use it as data storage for backups.
Is it possible? 

I very appreciate quick reply, my boss wants me to finish backups config next week...

Best regards
Kamil Tunkiewicz

backup never finishes

hi,

I would hope the backup would have finished by now after doubling the 
server memory. The backups of the same client of all the other 
partitions over a 1Tb of space work fine.

Backup server 32G of ram Backuppc Version 3.2.1, client Ubuntu 12, 132Gb

NewFileList.0 May 2 06:25
NewFileList has not updated since May 2 14:28, XferLOG.z May 2 19:44

file count is ~850k no recursive links

  strace -p 4817
Process 4817 attached - interrupt to quit
select(16, [6], [9], [6 9], NULL)       = 1 (in [6])
select(8, [6], NULL, [6], {0, 0})       = 1 (in [6], left {0, 0})
read(6, "log   pool     664 9531/1052    "..., 65536) = 120
select(16, [6], [9], [6 9], NULL)       = 1 (in [6])
select(8, [6], NULL, [6], {0, 0})       = 1 (in [6], left {0, 0})
read(6, "log   pool     664 9531/1052    "..., 65536) = 124
select(16, [6], [9], [6 9], NULL)       = 1 (in [6])
select(8, [6], NULL, [6], {0, 0})       = 1 (in [6], left {0, 0})

What else should I be looking at?

Mark

C$ or C:\ ?

Does BackupPC see these two shares differently? Which to use?  Why?

Thanks.
