There are several reasons: - BackupPC was deployed first and it works well. Never change a running system if it suits all your needs (so far). - We're backing up multiple hosts over Internet. Rsync saves us a lot of bandwidth. - Bacula has two purposes for us: provide offsite backup to tape and store our database dumps (where BackupPC isn't good at because the files change each day - about 70Gb each day) - IMO it is easier to restore files to a server using BackupPC - e.g. after reinstall - it just needs ssh running and rsync installed. - I didn't like the extra bacula client on servers. But I didn't look deeply into it either. - BackupPC has a nice Web interface. We've had troubles finding a working bat when we installed Bacula (it might have been improved, but I'm a bit anxious to update our Bacula 2.2.x to 3.0) - we're a SuSE shop and had lots of segfaults etc. Counter-question: Why should I use Bacula instead?

Exactly. Something like
# If set to 1, wait for running backups to complete before running
# BackupPC_nightly. Also, no new backups will be started until the
# nightly cleanup is finished.
$Conf{NoBackupsDuringBackupPCNightly} = 1;
By the way: The same should be configurable for the trash cleaner. It
does about the same to disk I/O as the nightly - it make the disk head
spin around like mad since a lot of virtually random inodes need to be
touched. Therefore, a config like
# Configure trash cleaning strategy:
# 1 = continuous - wake up every $Conf{TrashCleanSleepSec} and check for
# files to delete (default pre 3.2 behaviour B-) )
# 2 = run only just before BackupPC_nightly - see
# $Conf{DelayBackupsDuringBackupPCNightly} to disable backups during
# that operation
$Conf{TrashCleanMethod} = 1;
Hm... does anybody volunteer to implement that? I could take a look and
try to figure out a patch but I've not yet digged into the BackupPC
scheduling code...
Tino.

[BackupPC-users] Merge config in per-host config?
Apologies if this is a FAQ, but it seems I'm not able to merge the per-host
config with the general config. In config.pl, I have
$Conf{BackupFilesExclude} = {
'/' => [ '/proc',
'/dev',
'/sys'
]
};
For a specific host, I want to exclude some other directories, so in the per-
host config file I'm doing
$Conf{BackupFilesExclude}{'/'} = [
@{$Conf{BackupFilesExclude}{'/'}},
'/var/spool'
];
However, when the backup runs, it seems that the only exclusion is /var/spool,
instead of '/proc', '/dev', '/sys', '/var/spool' as I would expect.
I'm surely doing something wrong, but I cannot find out what.
Thank you in advance.

That's correct, but it hardly seems to matter. Due to a problem the offsite machine was down once for over two weeks, and the subsequent synchronisation run still only took 14h.

Yes, i was wrong. A crash during the catting would normally not hurt the files that already were transmitted.

Re: [BackupPC-users] Advantages of internal over external hard drive?
For anything any of us (consumers of free backup products) are likely to do, anything stronger than original DES is probably fine. If you want background info, http://www.security-forums.com/viewtopic.php?printertopic=1&t=6690&start=0&postdays=0&postorder=asc&vote=viewresult&sid=19654e84950fe8608fde7e4a951da0ee has a good end-user perspective of some of the most common ciphers. The take home is: avoid DES due to the short length of its key. 3DES is secure (30+ years of use), but slow. Blowfish has a good reputation for being fast, simple, and secure. If you're paranoid, think about AES, but remember the recent advisories concerning AES keys >= 128-bits.

Well, BackupPC has a different but arguably more sophisticated and robust version of backup scheduling. If all you want to do is to run a fixed backup job at the exact same time every week, then you don't need to use the sophisticated default scheduler.

Backuppc is designed to schedule itself automatically so as to fit as many
backups as possible into an allocated window. It is best to do this if
possible. (Using 'blackout' periods).
If for some reason you need to explicitly schedule a backup for a particular
time; this is best done with a cron job.
For example, to make a full backup go off every day at noon, put this in
your /etc/crontab:
00 12 * * * backuppc /usr/share/backuppc/bin/BackupPC_serverMesg backup
host.example.com host.example.com backuppc 1
You may or may not want to stop backuppc from automatically scheduling a
backup of the same host. This is done by putting:
$Conf{BackupsDisable} = 1;
in the per-host configuration file.
The best documentation is the comments in the config.pl file. Read that
end-to-end, and you'll understand 90% of how backuppc works.

In my case I only have one server, so I do not need the software to manage scheduling the default way. In a small network of two or three computers the sophisticated scheduling is an overkill. I think this type of networks are the most found since home users and small business networks are the majority over large business networks.

Re: [BackupPC-users] Really confused with scheduling
Another doubt:
The BackupPC_nighly job does not do any actual backup, right? It only does
housekeeping jobs?
I should set a cron job for the BackupPC_nightly job and set
$Conf{BackupsDisable} = 1;
Or leave $Conf{BackupsDisable} = 0 and set $Conf{BlackoutPeriods} to every
day/hour to simulate BackupDisable = 1
Or what do you suggest would be the better way?

The backup will show as running in the web status. However you only get
email status reports if a host has gone more than
$Conf{EMailNotifyOldBackupDays} without a backup and even then not more
often than $Conf{EMailNotifyMinDays} between emails.

Re: [BackupPC-users] Really confused with scheduling
Actually I could go by setting the time by using the WakeupSchedule and having all backups run at the same time, But I do need to have the Full backup to run in a certain day and the Incremental(s) on the other days. By setting Blackouts you can set a window within a day but is always the same window for all backups, so how can I make the Full backup only to run on Sunday or any specific day of the week? I see that I can set the period between Full backups and Incremental(s), but that is once the first backup is run the periods take place, but, when the first backup is going to run? What I see is tonight will be the first Full backup if I set the BackupsDisable to 0 today. I do not think that is a good way to set the start date of the backup sequences. One should be able to set at least a start date for each of the Full backups for each Host in a deterministic way, then letting the scheduler take the control.

Re: [BackupPC-users] Really confused with scheduling
I set my $Conf{EMailNotifyMinDays} to 1 to be able to receive an email every
day.
If I set $Conf{EMailNotifyOldBackupDays} to 0, will I receive an email every
day for each host backup?
I need to receive the email for each host for each backup run.
If the software does not do that then I have to set a cron job to send me
the status to the email regardless?

Is it 'safe' to exclude the other parts of System Volume Information if you want to do as clean a restore as possible? Yes, System Volume Information is only used to "go back" to a previous set point, so it's substantially redundant. Excluding it means you can't go back to an earlier set point, but presumably, you could simply restore an earlier backup.

If I were doing it (and cared about down-to-the-second scheduling), I'd
leave most things at the defaults and set
$Conf{FullPeriod} and $Conf{IncrPeriod} to times that will never be
reached as long as the cron-initiated runs happen when you expect. I'm
not sure there is good locking between scheduled runs and ServerMesg
jobs so be sure you allow enough time for your jobs to complete and
reset the scheduler's timer.

Re: [BackupPC-users] Really confused with scheduling
If I set my FullPeriod to 10 (days) and the cron job runs every Saturday (7
days), the FullPeriod will not be reached?
The BackupPC_nighly job will recognize the cron job backup data and will
remove the old backups?

Correct. I suggest you try installing the software, reading the config.pl, and the wiki pages.

I agree that it should work like that. However, if I'm not mistaken, it seems
that what's written here still applies:
http://osdir.com/ml/sysutils.backup.backuppc.general/2003-10/msg00010.html
As it happens, I was having the same issue in the office, so I changed the
source to "do the right thing". Of course this is a hack, though it seems to
be working for me, but I'm still testing it because it might break something
else. Here is the patch (for rel. 3.0.0 sorry, but I've checked and the
relevant bits have not changed in 3.1 and 3.2):

In short, it allows reading the per-host config file with the configuration
already read in the general config in effect, instead of an empty one.
If I've got the program logic right, and that doesn't break anything (which of
course is not granted, as I'm not a real Perl programmer anyway), may I ask
that the change be incorporated in the vanilla BackupPC code?
It doesn't break compatibility with those who are already using the per-host
config to override (rather than add to) the values, but it adds the
possibility to append values, which is very important when you have tens or
hundreds of hosts and almost each of them needs some minor change from the
basic config. Otherwise, you'd end up replicating almost the same things in
each per-host config file, and that is a pain if you later need to change
something in the common bits.
If my patch does it the wrong way, then may I still ask for that to be added
as a feature request?
Thank you for your consideration.

Re: [BackupPC-users] Really confused with scheduling
Yes, finally. I got it. I can set a deferral time for each host in such a way that the first Full Backup starts the day and time I want it to start, then the Incremental(s) will follow the correct sequence, and so on. This way we can set indirectly the start date and time for each backup without using the cron job method. Maybe this is in the FAQ or the WIKI, but if not will be nice to be there.

But maybe the global config could be made available as $GlobalConf{xyz}
within the per-host config? I remember having tried the same thing -
that is, I want a set of default excludes, then extend then for one
host. Currently, I have to repeat the whole default config just to
append one more directory to the excludes.

That's actually another issue we're having, which would be solved by my patch.
We have a set of basic rsync options in config.pl (that is, $Conf{RsyncArgs}
and $Conf{RsyncRestoreArgs}) which do not include --checksum-seed=32761, as
some of the hosts we back up have a too old rsync version installed. But, for
the hosts that DO support that, we want to use it. So my patch enables us to
do something like
push @{$Conf{RsyncArgs}}, '--checksum-seed=32761';
push @{$Conf{RsyncRestoreArgs}}, '--checksum-seed=32761';
in the per-host config file only for the hosts that can support that. The
alternative would be to include the full $Conf{RsyncArgs} with checksum
caching appended at the end in each per-host config file. If some day we want
to change an option in rsync's default options, we would have to change that
in config.pl AND in all the per-host config files where we were forced to
paste the same options only to add checksum caching, which would be
inconvenient.
So far, we were able to kind of simulate the same behavior by doing, in each
per-host config file,
do "/etc/backuppc/config.pl";
# host specific stuff here, including appending of values
...
but that looks like a hack to me.

Well I see your point, but keep in mind that the two behaviors are not
mutually incompatible; people who used to override values in the per-host
config file can still do so (in fact without changing anything); on the other
hand, my suggestion would allow you to get additive behavior *only if you
want*, because to do that you have to explicitly craft Perl code like the
above or similar, which should mean you know what you're doing.

[BackupPC-users] XP rsync SLOW and fails
Welp, I'm not REALLY sure what I did, but I had all of half an hour to tinker with the bosses laptop. I tried newer matching versions of rsync and cygwin1 as taken from other packages mentioned previously and tried them on the stock c:\rsyncd folder distribution. They didn't work too well as the rsyncd.conf needed altering from: [cDrive] path = c: comment = Entire Drive to: path = /cygdrive/c/ I ended up returning back to original files when it wouldn't start properly or backup failed for one reason or another. I simply didn't have the luxury of time to document all the versions of rsync.exe and cygwin1.dll. One pair came from Delta Copy though, another from the goodjobsucking.com site.

Personally, when administrating a machine I try to avoid being too clever
with my configurations. One needs to consider that another administrator may
come along and have little or no clue how things are set up with all the
levels of indirection and dependency. As such, I often take some extra
effort to explicitly spell out what all the settings are such that the
behavior may be readily discovered.
That said, I also realize that I don't know what's best for everyone else,
and it's good to have labor-saving flexibility and configurability. So long
as the default behavior remains; it seems like a reasonable patch.

How did you configure your incrementals? Do you have incremental levels configured? If yes, how? They might cause your difficulties - if you had 29 incremental levels, the server would have to traverse a whopping 28 backups on the 29th day!

Perhaps I misunderstand by why couldn't the config.pl be read in
and evaluated first followed by reading in the appropriate
pc/hostname.pl file if it exist.
Then:
1. Any statement in subsequent pc/hostname.pl files of form
$Conf{x} = "";
would clearly overwrite earlier settings.
2. Any missing $Conf variable in the pc/hostname.pl file would inherit
from the config.pl file.
3. And something of form:
push(@{$Conf{x}}, "");
would append to the value set in the main config.pl file
The only issue is that for some variables form #3 might not make sense
but then don't use form #3 or use another snippet of Perl code to
properly make your edit.

Doesn't that happen by itself if you use the web interface to edit the
per-host config? That is, you see all of the default array elements
from the main config file until you insert a new one and then the set
becomes an override. If you have enough machines that you don't want to
use the web interface to make a change, you could use a script to make
whatever edits you want.

I'm not using the web interface for configuring my hosts, for example
because I've got a
do "somepath/DefaultRsync.conf";
in several config.pl. I just would like to say "add this to the default
excludes list" in config.pl which should be pretty easy given that it is
Perl code already.

[BackupPC-users] XP rsync SLOW and fails
Hello Tino, Thank you for bringing that to my attention. I have full period set to 29.67 with all other parameters as default except for full keep count as 2. Inrementals are all default. Blackouts set to zero for the laptops so I can specify the hours tailored to each user. Reason for the Full being as it is... One full per month is fine with me so the user is not burdened with an unresponsive, or slow laptop. The incrementals backup all data since the last full there four even though I only have 6 incrementals available they contain all data since the last full, right? sure there is a gap between the last full, say at the beginning of the month and an incremental toward the end of the month, but I am not too worried about going back any further than the six days. If worse cam to worse and a rebuilding of the laptop were to be forced upon us, we'd restore the full and the last incremental, right? So, unless I'm missing something, I should be okay. I'll gladly take your opinions, I just don't want the user to be aware that the backup even runs during the day. Now, at night, for those users who LEAVE their laptops at the office, that is another picture. I will set the period to 6.97 and leave the full keep to 2 to conserve space. I hope I am being prudent, yet efficient. Your thoughts?

The network connection between them is indeed quite fast, but that doesn't really matter.

That's a conforting thought. But it is maybe possible to add write support to my script, and use that on the remote side. That way you would build a real remote mirror device immediately, instead of a set of files that can be used to reconstruct it. I'll try that one of the next days.

Re: [BackupPC-users] XP rsync SLOW and fails
You're missing something, I believe. Using rsync, only the *first* backup actually transfers every file -- every other file will avoid transferring files that are duplicates. It may be worthwhile to review the backup times in your logs. Since incrementals go back to the last full, it wouldn't surprise me if an incremental backup against a 29-day-old full could actually be slower than a full backup. Some experimentation here demonstrated that the optimal full backup period is actually about a week, and after about 10 days, the incrementals took as long or longer than full backups. Again, this is rsync; smb is quite different. > Hello Tino, > > Thank you for bringing that to my attention.

It is, but you can't just re-assign the existing variable without losing
what's there. If you are adding new perl code and have given up on the
web edit mechanism, you can just push elements or define a new array and
combine them:
@old = (@old, @new);

Re: [BackupPC-users] Advantages of internal over external hard drive?
Thank-you to everyone for their suggestions. I think I will go with an external eSATA drive. The P3 may not be fast enough, in which case I assume moving to a faster machine will be easier with an external than an internal drive. Please let me know if this is not the case! I was looking on newegg, and found 1TB drives for less than $150. However, they are advertised to be eSATA compatible for DVRs. Are they also compatible as backup devices? I was looking at this one in particular: http://www.newegg.com/Product/Product.aspx?Item=N82E16822186175 Do you have any recommendations for a PCI 33MHz eSATA drive controller for external eSATA drives that works with Debian?
