$Conf{FillCycle} with exponential expiry with V4

Hi,

i am trying to understand the new concept of backup with the V4.

i understand "reverse deltas" and how it works but the new variable $Conf{FillCycle} makes me confused...

For example, i would like to have 1 full backup per week, one full per month and one full per year during 3 years.

I put this in configuration :

FullPeriod: 6.97
FillCycle : 7
FullKeepCnt : 4, 0, 12, 0, 0, 0, 3
FullKeepCntMin 1
FullAgeMax 90

IncrPeriod 0.97
IncrKeepCnt 6
IncrKeepCntMin 1
IncrAgeMax 30

i put 7 in FillCycle with no conviction...

Is that right ? i read the documentation but i am not english and some terms are difficult to traduct..

Thank you

lastlog


Can someone please put the situation in Linux with not filtering
/var/log/lastlog (sparse file) somewhere in the docs. It comes back to
bite me every few years and I waste a bunch of time figuring out why rsync
keeps aborting. Or for that matter just hard code ignoring that file.

State idle

Hi!

Currently I have installed BackupPC on a server and I have configured two hosts to support the automated backups worked fine until recently, but now can not be performed on an automatic but if I make these manually if generated. I've checked the settings and was 0 BackupsDisable also check the logs but did not indicate error.

When I check this summary Host has idle state

Please, if you can help me.

Regards

[Backuppc] Problem with tab order in config page

Hi,

I have a weird problem with my new backuppc instance and I was hoping someone would be able to give me some hints.

Technical informations :
ubuntu 14.04.1
apache 2.4.7
backuppc 3.3.0 (installed with apt-get install backuppc)
browsers : linux FF 34, windows FF 32, IE 10

It's working fine, I have been able to do all the setup I wanted, but it's acting strangely when I click in the "edit config" page.

whenever I click on a tab (like "Email", "Xfer", "CGI", ...), the tab order changes. It will behave the same way in the "edit config" page of a host, and the order of the tabs appears to be totally random.

It's not the bug of the century, but it's rather annoying ...I did not have the problem with BackupPC 3.1 & 3.2

I have tried to look for this issue elsewhere but could not find anything related. Has anyone any idea regarding this ? (problem with javascript ?)

Thanks a lot,

Nicolas

How to gain access to a backup that is no longer listed.

Hello,
I recently started using Backup PC  version 4.0.0alpha3.
It was just in time to allow me to backup a file server with approximately 1.6TB of data before the file server crashed.
After replacing the failed hard drives, I was using backupPC to restore the files from backup#53.
However an error  caused the full restore to fail and started doing the restore in parts.
After a portion of the restore run (it took three days because of the network speed and the volume of data) a backup of the server started to run immediately.
This back up is listed as Backup#0.  All previous backups are no longer listed. I was not finished restoring the files from backup#53.
How do I gain access to the unlisted backup?
While the backups are not listed the pool size has not been reduced, which suggests that the backup files are still there.
I look forward to assistance in this situation.

May Yahweh bless you and keep you.
May Yahweh let his face shine on you and be gracious to you.
May Yahweh show you his face and bring you peace.
(New Jerusalem Bible Numbers 6:24-26)

Changing backup browsing view from bytes to eg megabytes

Hi all,

When I browse a host's backups, there is a size-column showing the file size in bytes.

Can this be changed somewhere to show megabytes, or even gigabytes instead?

I've looked in /usr/share/BackupPC/lib/BackupPC/CGI/Browse.pm and found this bit, which looks promising:

                #
                # This is the selected directory, so display all the files
                #
                my ($attrStr, $iconStr);
                if ( defined($a = $attr->{$f}) ) {
                    my $mtimeStr = $bpc->timeStamp($a->{mtime});
		    # UGH -> fix this
                    my $typeStr  = BackupPC::Attrib::fileType2Text(undef,
                                                                                                             $a->{type});
                    my $modeStr  = sprintf("0%o", $a->{mode} & 07777);
                    $iconStr = <<EOF;
<img src="$Conf{CgiImageDirURL}/icon-$typeStr.png" valign="top">
EOF
                    $attrStr .= <<EOF;
    <td align="center" class="fviewborder">$typeStr</td>
    <td align="center" class="fviewborder">$modeStr</td>
    <td align="center" class="fviewborder">$a->{backupNum}</td>
    <td align="right" class="fviewborder">$a->{size}</td>
    <td align="right" class="fviewborder">$mtimeStr</td>
</tr>
EOF

Can't find where "$a->{size}" comes from though.

You got any pointers for me guys?

Thanks.

Migration to Backuppc

Hello,

We have installed backuppc on our backup server.
It's working fine.

Before we were using scripts with rsync on this server.
I have a folder for each host.

I would like to know how I can use the data that already exists on my backup server.

2 hosts are using about 3 TB  and 4 TB of data, I would like to avoid to sync them over the network again,
and use the local backup to create the complete backup of backuppc.

Is this possible to convert or move the data from a local folder to the backuppc storage ?

Thank you for your help.

status

Hi,
I would like to have, if possible, some information about current status of BackupPC development.
Latest sources found on SouceForge are almost one year old and CVS do not seem to be used much.

I am now in the process of evaluating its usage on an oldish NAS (I had in-house), before acquiring a bunch of
newer ones for deployment, but I don't want to be tied to some unmaintained software, of course.
If evaluation goes reasonably well I am willing to prepare an OptWare iPackage out of BackupPC, possibly
with some script to automate client setup.
Obviously such an effort would be nearly wasted on a dwindling product.

Current tests tell me bottleneck in my setup is CPU.
I am trying now to ease the problem by using less compression and rsync checksum caching.
Is there some utility to uncompress cpool to pool and contextually compute rsync checksums and caching them?

TiA
Mauro

searching BackupPC_fixLinks.pl

Hi,

in the pc dir of one of my hosts I have several files which have no link to the cpool.  I read about BackupPC_fixLinks.pl of Jeffrey Kosowsky.  However, I'm unable to find it.  The link http://sourceforge.net/apps/mediawiki/backuppc/index.php?title=BackupPC_FixLinks is broken, and I can't find it anywhere in one of the tabs on the new backuppc sourceforge page.  Where can I find it?

Best regards,

Michael

Using NFS to increase backup speed

Hi all,

I'm seeing network speeds at about 35-45 Mbps when using BackupPC and rsync over ssh.

Running iperf below I notice the network should theoretically be capable of a bit more than that. I
understand that ssh adds quite a bit of bottleneck.

[root <at> titan ~]# iperf -c cyndane
------------------------------------------------------------
Client connecting to cyndane, TCP port 5001
TCP window size: 42.5 KByte (default)
------------------------------------------------------------
[  3] local 192.168.0.8 port 51754 connected with 192.168.0.9 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec   398 MBytes   334 Mbits/sec
[root <at> titan ~]#

Just to clarify, titan above is the BPC-server and has some local disk space where the backup pool is.
Cyndane is the host being backed up. Both have gigabit-NIC's and a ditto switch between them.

After reading one of the answers at
<<http://serverfault.com/questions/377598/why-is-my-rsync-so-slow>>, I kinda' wonder if the
NFS-angle would work for use with BackupPC and how I would go about it. Is the tar transfer method the only
one supported by BPC if using NFS for example?
Rsyncing a NFS-mounted remote host supposedly is a lot faster than doing rsync over ssh.

Any thoughts on this? 
Has anybody on this list maybe set up their systems using NFS and can share their experience?

Thanks.
