Well in the config.pl file I have:
$Conf{BlackoutPeriods} = [
{
'hourEnd' => '11.5',
'weekDays' => [
0,
1,
2,
3,
4
],
'hourBegin' => 7
}
];
I don't see any mention on the host summary page of blackout period.
Should I try to set BlackoutGoodCnt to -1 to disable that feature?

It is possible. You could either instruct BackupPC to do full backups
only (set $Conf{FullPeriod} = 0.97 and $Conf{FullKeepCnt} = 3660). Or
configure Full and Incr backups accordingly:
(10 years, every 7 days)
$Conf{FullKeepCnt} = 523;
$Conf{IncrKeepCnt} = 3137;
How many clients are you talking about and how much data is on them?
You're talking about a pretty HUGE amount of data. I'm wondering which
machine, disk subsystem and file system will be able to handle that. You
might be talking about billions (10^9) of files here.
And don't forget a second layer of backup: What if your backup server
crashes hardly or burns down? What if some subtle file system bug is
triggered and eats all your data? Every file which is stored in only one
location has to be considered lost.
HTH,
Tino.

I meant the per-host page. No need to change the blackout settings
unless the description there looks wrong.
I'd recommend running BackupPC_dump manually with the -v option (not
the -f option):
su backuppc
BackupPC_dump -v HOST
It should print why it doesn't do a backup.

[BackupPC-users] do a manual fill of a backup
Does anyone know how to do a manual fill of a backup from the command line? what I am doing is changing incrementals to fulls and fulls to incrementals. when going full->incr there is not problem but when going from incr->full I would like to do the fill process on that backup. I don't know that it really matters that much in the end but I want to know that there is a copy/hard link of every file in this 'full' backup. I am aware of the circumstances that an incr backup wouldn't be complete or wouldn't be as thorough in checking for file changes but in my circumstance my files always have their mtime changed.

Re: [BackupPC-users] file extraction, windows
I think that this has been hashed over for some time now. It seems that windows will only handle a 2GB zip file via the CGI interface for no apparently good reason. You can either do BackupPC_zipCreate on the backuppc machine and save it to your windows machine via samba or something OR you can just choose tar for your restore and then compresses that if you like.

Yeah, but Tino's question was why you'd want to use zip instead of a compressed tarball, because metadata like permissions and ownership can't be stored in a zip file (AFAIK). You could also create a tar archive and encrypt that, right? Or store the archive on an encrypted volume.

Re: [BackupPC-users] Archive encrypted zip
I thought of zip as a good solution for achieving encrypted backups. But you are right here, it will lose metadata. My only requirements are that archives must be encrypted at the file level (forget encrypted volume) and that I can open those under Windows (using Winzip for example).

Re: [BackupPC-users] Backup to USB disk.
I think I understand your want in that you would like to have backuppc check that a drive is hooked up before trying to use it for backups. If I am correct then I would suggest you build a quick daemon script that starts backuppc when the device is hotplugged and stops backuppc when unplugged. I dont know what your linux distro is but hotplug scripts are pretty easy, do some google work to get the file and method for a hotplug script on a specific device.

Re: [BackupPC-users] Backup to USB disk.
Hi Daniel, No, not quite. If you want a clean file system on the drive you are going to remove you must temporary stop BackupPC and unmount the file system first. When the drive is removed you can mount the file system again and start BackupPC. This will cause the RAID to run in degraded mode if you only have one disk left in the RAID, but will otherwise work as usual. (You don't have to run in degraded mode if you are rotating four disks in the scheme I proposed.) Stopping BackupPC and unmounting the file system can't be done by hotplug, because it is already too late. You don't have to stop BackupPC when you attach a drive. Just plug it in and add it to the RAID with "mdadm --add", which you might be able to get hotplug to do for you.

[BackupPC-users] # of files per backup job
Hi can anyone comment on back jobs with lots of files effecting transfer time? I have 2 big backup jobs which are taking too long over a WAN link. Would it be advisable to break the jobs up into many smaller jobs with fewer files / job? Would I be gaining anything? would 10 jobs with a 100,000 files each complete faster then 1 job with 1,000,000 files if they were backing up the same information thanks - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

You may also want to look at latency and any packet loss between the two endpoints. If you are backing up GB of data even a T1 is pretty slow, especially if you have other data going across the same link, it could create an inadvertent "DoS" if you peg the whole connection. If you are using rsync, and especially if memory and / or CPU is a bottlneck, breaking it up into smaller jobs could help by reducing the size of the "list" that rsync has to build and transfer. Having a lot of files will increase the size of the list. What I have done in some cases is to just "mirror" what I want to backup across the link to a "separate drive" at the remote end and then use BackupPC at the remote end to make a "backup" of the mirror. The "mirror" is just a copy of whatever is on the original, but BackupPC provides the "history" of changes over time so you have more than just last night's backup. That also helps for initial set up since I can use e.g. an external USB drive at the local site, do the initial mirror via USB rather then over the WAN link, and then physically take the USB drive to the remote (or maybe in your case ship the drive) and plug it into the server there. Optionally, substitute eSATA / SCSI / iSCSI / IEEE 1394 your connection type of choice for USB. Backing up many GB over T1 will take several hours, especially if you limit bandwidth so that it does not just peg your T1 and put everything else out of commission until it finishes. For e.g 20 GiB * 1024 MiB / GiB = 20480 MiB / 1.544 MiB/s = 13264 s / 3600 s/ hour = 3:41 hours That would be for an optimal point-to-point T1 ignoring bandwidth lost to framing bits, in practice will most likely take quite a bit longer than that, especially if it is through VPN across the internet with possible congestion at routers along the way. > > > would 10 jobs with a 100,000 files each complete > faster then 1 job with 1,000,000 files if they > were backing up the same information > > thanks > > > - > This SF.net email is sponsored by the 2008 JavaOne(SM) Conference > Don't miss this year's exciting event.

Re: [BackupPC-users] Archive encrypted zip
for a high-compression AES 256bit encryption you can use a tar.7z. you need to wrap the files in tar to preserve permissions and meta data and then 7z it with AES. 7z is also a very powerfull compressor, better than zip or gzip and can match bzip2 but be faster. you could technically use 7zip to make AES encrypted regular zip(pkzip style) zip files. Alternatively, you could just use tar.gz and then encrypt that file with another program.

Re: [BackupPC-users] # of files per backup job
technically, you wont have any difference in backup speed by splitting up the job. you might be running into a system resource issue on the server or client because rsync will eat up large chunks of RAM as file count increases(rule of thumb is 100Bytes per file) which may mean your system is pushing everything off to swap, making the server run very very slow. another likely issue is that with many many files, IO on EITHER the server or the client could be a bit bottleneck. I do a large rsync transfer over a T1 line nightly, I mirror my backuppc server remotely each night. this is a pretty long process even though I only have about 1GB of new data each night. The math says that can be transfered in about 1.5 hours but the initial file list takes 10 minutes to compute and IO performance is a bottleneck so the transfer takes about 2.5 hours, more or less depending on the amount of backup data.
