Might you simply need to increase your $Conf{ClientTimeout}?
It would make sense that your backups take longer with busy client machines
than with idle ones, after all.
Interesting suggestion. I will try to investigate more in this direction. I
don't know exactly was should be done as a matter of test though, as the
errors aren't reproduceable, as I mentioned in the beginning.
yes, there are always some things you can't really test :-(.
You could look at the logs of your failing backups though and check whether
the time they ran seems to correspond with your current (resp. former)
setting of $Conf{ClientTimeout}. If that is set to 7200 s (2 h) and you have
failed backups running 30 min, 43 min and 22 min and good ones running 15
min, 35 min and 65 min, then that's obviously the wrong track. If your good
backups are comparatively short though and the others fail after roughly 2
hours, I'd simply try maybe doubling the value and seeing if the failures go
away. As I understand it, $Conf{ClientTimeout} is not a value that needs to
be fine tuned to be only slightly larger than your longest backup, but
rather a measure to eventually detect and kill hung backups. The only really
problematic 'resource' a hung backup seems to consume is that it counts in
terms of $Conf{MaxBackups}, thus preventing or postponing running other
backups (well, yes, a hung rsync might consume a considerable amount of
(swappable) memory). I've read of people using timeout values of 72000 (20h)
or more.

Are we near to another beta release, or will there be a RC release (or even 3.0.0) in the near future? I must say that I have been *extremely* happy with BackupPC 3 so far.

On all of the servers we have installed the latest beta I have seen a
problem with the blackout periods. They appear to be ignored or

I am using the default blackout periods and schedules in all my configs
but all the incremental backups are starting in the middle of the day,
11am mostly.
By default, Blackouts only apply after a host has been successfully
pinged 7 times in a row, which could be ~1 week of elapsed time.
A sequence of 3 failures (eg: host down) resets the count.
Look in the host summary page and you should see text like:
- Pings to HOST have succeeded 77 consecutive times.
- Because HOST has been on the network at least 7 consecutive times,
it will not be backed up from 1:00 to 8:00 on Sun, Mon, Tue, Wed,
Thu, Fri, Sat.
What does your's say?
Finally, please check your settings of
$Conf{BlackoutPeriods}
$Conf{BlackoutBadPingLimit}
$Conf{BlackoutGoodCnt}

The proper way to do it is to create an archive request file (see the CGI code to see how to do that) and to use BackupPC_serverMesg to send an archive request (again, see the CGI code to see how to do that) to BackupPC.

that looks like some fantastic work!! Certainly something that i think
is worthwhile. I only wish i knew perl so i could knock out stuff like
this ;)
I haven't tested myself, but if you have a sample email/rss output could
you post so we can see what it looks like?
Has this been added to any feature requests? implemented in version 3?
If not i would like to see it become a feature. A daily email to send to
an admin about the status of the system and good/ bad backups etc is
worthwhile. In my experience sometimes the end user in charge of
monitoring the state of hosts being backed up is a little slack.

I really don't like programs that annoy you with emails. That said,
I agree there hasn't been a way to be sure BackupPC is running ok.
In BackupPC 3.0.0beta there is a new option to BackupPC_sendEmail:
-c check if BackupPC is alive and send an email if not
That allows you to run BackupPC_sendEmail -c from cron and
it will send an email to $Conf{EMailAdminUserName} if it
can't contact the BackupPC server.
The existing email options should handle the cases where BackupPC
is running but backups are failing.

You could disable automatic backups and schedule eveything from cron
using BackupPC_serverMesg.
Or you could
- set $Conf{FullPeriod} to, say, 0.9,
- set $Conf{IncrPeriod} to 2/24 = 0.08,
- use blackouts on the midnight - 6am and 6pm-10pm windows
- kick things off by starting the first full backup at 10pm.
The drawback with this approach is there no guarantee that the
full backup won't shift to during the day (eg: if a server is
down).

[BackupPC-users] CGI scripts to manage removable hard drive media.
Hello! Here are the scripts I use to manage the removable hard drive media used to store daily archives of my backup servers via the GUI, instead of from the command line. Briefly, the system is set up like this: BackupPC's pool is stored on a large internal hard drive. Every day at a little after 7:00 A.M., the backup server starts an archive of each host, which is stored on a second hard drive that is mounted in a removable tray. Once this is complete, the user can shut down the server, remove the hard drive, replace it with a different one, and turn the server back on. Once the new drive is in place, it is repartitioned, reformatted and remounted in place, ready for the next archive. There are two scripts that make this happen. The first one simply shuts the server down. The second one handles the repartitioning, reformatting and remounting. There is absolutely no reason why this couldn't be handed by simply ssh'ing into the server. Except that these servers are destined for network administrators for whom the command line is a tremendously evil thing, and if you try to sell them a solution that contains instructions like Use putty, log into the server and type this command, they will say no. Hence, the CGI scripts... Because the scripts will be run by the webserver, they will be run with its permissions, which likely do not include the ability to shut down the server, or other such commands. The way I have done this is to use sudo, with the proper lines in sudoers. I've tried to make the commands as specific as posssible, to avoid possible security issues. To partition the drive, I am echoing responses to the fdisk command. I looked into parted, but I could not find a clean way of getting it to create a single large partition without knowing how big the partition was. Seeing as this will be used with drives of different sizes, I decided to stick with fdisk. Also, the HTML files that are cat to the user are created simply by saving any old BackupPC HTML page to a file, and chopping the part before the main body DIV into the top file, and the part after the main body DIV into the bottom file. If you have any suggestions as to how to make this script better, I would be happy to hear them. Otherwise, I hope they are useful to someone else.

[BackupPC-users] What happens, if client rsync process crashes?
Hi all, I am very new to backupPC - and I like it more more and more every day. ;-) I made a direcory with four 1MB files and some smaller text files for test purposes. Today, I tried some error cases and killed the rsync process on my client machine while syncing with xfermethod=rsync. After killing the process, the cgi interface showed this backup run as OK, but most of my test files were not backed up. The files transfered until my interrupt seem to be in the archive, all other files lack. Is this the expected behaviour? If yes: How can I distinguish between an correctly backed up archive and an archive, that is half backed up due to a process crash on the client machine? Thanks a lot, Clemente Btw: I use backuppc as packaged by debian maintainers (sarge).

Has this been added to any feature requests? implemented in version 3? If not i would like to see it become a feature. A daily email to send to an admin about the status of the system and good/ bad backups etc is worthwhile. In my experience sometimes the end user in charge of monitoring the state of hosts being backed up is a little slack. Maybe a project like this can be integrated into BackupPC: http://sourceforge.net/projects/backupmon ? Michael. - Take Surveys. Earn Cash.

[BackupPC-users] Switching cipher
Hi, Just wanted to share this interesting test result I found about switching the ssh cipher. I am running the 3.0.0 beta3 in production on a fairly small centos4 server (basic spec but with a 1.5TB raid5 setup) and backing up a variety of windows, linux and solaris across a 100mbit lan. I wanted to see whether I could speed up the data transfer without resorting to rsh or applying the no-encryption patch for ssh, so I did some tests and found that arcfour was the fastest cipher for me (seems to be a common conclusion), by a factor of about 2. Interestingly when I start using this in the backuppc ssh config it has made huge improvements to the backup completion time by a factor of up to 10. Here are stats showing the difference, the cipher was switched after backup 21: Backup#TypeFilled Level Start Date Duration/mins Age/days Server Backup Path 15 fullyes 0 12/28 20:00 811.7 18.5 /home/backuppc/data/pc/oddball/15 18 incrno 1 1/1 01:00 124.9 15.3 /home/backuppc/data/pc/oddball/18 19 incrno 1 1/2 01:00 137.2 14.3 /home/backuppc/data/pc/oddball/19 20 incrno 1 1/3 01:00 124.2 13.3 /home/backuppc/data/pc/oddball/20 21 incrno 1 1/4 01:00 145.2 12.3 /home/backuppc/data/pc/oddball/21 22 fullyes 0 1/13 12:43 212.4 2.8 /home/backuppc/data/pc/oddball/22 23 incrno 1 1/14 12:14 7.7 1.8 /home/backuppc/data/pc/oddball/23 24 incrno 1 1/15 12:14 7.5 0.8 /home/backuppc/data/pc/oddball/24 Totals Existing Files New Files Backup# Type#Files Size/MB MB/sec #Files Size/MB #Files Size/MB 15 full269365 5971.7 0.1299242 863.5 180563 5115.6 18 incr2151256.2 0.03133521.2855 235.1 19 incr2161258.2 0.03150925.1686 233.2 20 incr2167260.2 0.03151826.2681 234.0 21 incr2173262.1 0.03124426.9962 235.3 22 full268940 5993.7 0.47268640 5722.1 11914 279.1 23 incr2136257.2 0.56159818.12965239.3 24 incr2142259.1 0.57149322.1682 237.1 I'd be interested to know if others have seen similar results.
