What files are in incremental

Hi,

Is there a way to tell what files are changed in an incremental backup?  
>From what I can see, the XFERLog shows all files.

Browse client backups w/o triggering backups

I am currently hosting backuppc on a server running Scientific Linux 6.1.

When I want to browse a disk that is not the current series of backups to find a file to restore using the CGI interface I always run the risk of a backup running on one of the clients and destroying the historical record.
Is there a way to start the backuppc daemon and disable backups globally?

Just to followup I did try remounting the disk read only but backuppc complains it can't make a hard link and dies.

Also, on a side note the wiki seems to have disappeared, I get a 404 error when I click the link on the email digest I receive.

Does rsync keep user_xattr on ext4?

Hi all,

I have not found any item proving this . Though, I assume it works fine.
I just want to be sure about it.

When backing up a Linux box with an ext4 fiesystem mounted with extended
attributes (user_xattr mount option) does BackupPC properly store all
attributes in the backup?

Does it restore all attributes in case? Or is there any additional stept
to be aware of?

Thanks

Christian

question about XferMethod 'archive'

Howdy,

I have a set of usb drives which I'll write archives to.

Using the web interface I can select hosts to archive, but
I want the selection to persist, ideally a script which will
be a cron job.

I've read the doc, but still don't understand what the script
would look like, where the list of hosts will go.

Thanks,
Kent

Anyone have a copy of BackupPC_DeleteFile.pl?

If a file from a full backup failed to transfer, what is the best way 
to make a subsequent, incremental backup include these (few) files? 

The remote system is a Windows system, reachable using rsyncd. 

If a full backup failed, then the next backup will be a full backup, but 
it will use the partial backup created by the failed full backup, which 
will include all changed files, up to (but not including) the file it 
failed on. I think this will mostly give you what you expect, just keep 
in mind when you say "(few) files" it actually means all files and 
directories after the file it failed on. 

So, you need to ensure that the largest file you want to transfer will 
successfully transfer without error within a single backup attempt. 

Is this new behavior? I'm using Version 3.3 (Ubuntu), and since skipping 
one file does not count as failure, and since that file isn't written 
since the full backup, it doesn't get backed up in subsequent 
(incremental) backups. 

Also, whenever theren is a connection problem, all the downloaded files 
from the next, incremental backup are thrown away. I'm currently 
circumventing that problem manually.

Rsync_bpc Error - BackupPC 4

I am using BackupPC 4.0 on a debian distro to backup two windows computers running Cygwin. I am using rsyncd
as the vehicle to back them up. When I try to start a backup, the backup fails apparently because of an
rsync_bpc issue. The log file entries are below:

following error message: “ERROR: failed to read a password from
/data/BackupPC/pc/agm-pc/.rsyncdpw5658”. 

Does anyone recognize that error and know what it means? It seems as though it needs some sort of password but
I don't know where to input a password. The only password I know of is in the secrets file on the target
Windows machines, but this looks like it is not even connecting to even get that far. 

Thanks in advance.

BackupPC-4.0.0alpha3 - Cant create a test hardlink between a

Igor,

I meant to reply to the group to let them know that the problem had been solved, but your email makes me think
that it has not been solved fully.  The script runs as user backuppc and apparently user backuppc did not
have permission to write to the data locations.  Once I fixed the permissions issue, the command start stop
command would work and give me an "ok."  

What makes me think that the problem has not been solved fully is that when I run the first two of your
commands, I get no response (as expected) and the testgram is created properly. However, your third
command does gives me an error that I don't understand.  Below are the results:

backuppc <at> linux-pc5:/data/BackupPC/pc$ touch /data/BackupPC/pc/testgram
backuppc <at> linux-pc5:/data/BackupPC/pc$ 

backuppc <at> linux-pc5:/$ ln /data/BackupPC/pc/testgram /data/BackupPC/cpool
backuppc <at> linux-pc5:/$ 

backuppc <at> linux-pc5:/$ rm /data/BackupPC/pc/testgram /data/BackupPC/cpool
rm: cannot remove ‘/data/BackupPC/cpool’: Is a directory

backuppc <at> linux-pc5:/$ ls -ld /data

backuppc <at> linux-pc5:/$ ls -ld /data/BackupPC
drwxrwx---+ 5 backuppc backuppc 4096 Jan 18 23:00 /data/BackupPC

backuppc <at> linux-pc5:/$ df /data/BackupPC

tune2fs 1.42.12 (29-Aug-2014)
tune2fs: Permission denied while trying to open /dev/mapper/dreux-root
Couldn't find valid filesystem superblock.

Is the output what was to be expected?  A couple of things are throwing me for a loop.  First, on the remove
command "rm /data/BackupPC/pc/testgram /data/BackupPC/cpool", should that really be "rm
/data/BackupPC/pc/testgram /data/BackupPC/cpool/testgram" and is that the nature of the Is a
directory error?  I presume so.  Or should my merely removing the linked target also remove the linked file?

Second, the "could not find valid filesystem superblock error is unclear.  

Thanks in advance.

Remote backup with VSS

Hi everybody,

I'm pretty new to BackupPC and I think it is a great software.
Anyway, I'm trying to use BackupPC on a VPS of mine to have remotely
backup pc. I backupped a couple of windows pc, better to say data
directory of couple pc, succesfully with cygwin + rsyncd from backuppc
sourceforge.

Now, I would like to try the same thing but with opened files so the
Michael Stowe solution seems the best chance using scripts to run
Windows shadow copy. Reading Michael's documentation here
http://www.goodjobsucking.com/?p=62 after completed backup there are
the points to close the entire process, I mean

1. postusercmd.sh
2. sleep.vbs etc..
3. unmaps drive etc..

Finally my question. Remote Internet backup is, of course, pretty slow
compared to LAN one, so what's happen if workstation to backup loose
its internet line, or if a customer get off pc ? Of course, remote
backup is not completed but BackupPC will be able to recover it ?
Shadows copy will still be there ?

Thank you.
Antonio

Usage of BackupPC in large environment

Hello,

I'm currently evaluating BackupPC as a backup solution and I have some 
questions to begin with.

My main concern is about the environment we're going to backup: we have 
~100 shared hosting servers.
This means that each server has:
~ 400 users
~ 300Gb /home partition
~ 8M files on each server

I know the pimary target for BackupPC is laptops and desktops: has 
anyone ever tried this software in such environment?

Regards,
