[BackupPC-users] Keeping 1 golden backup for a year
Okay, this kind of confuses me. I would like to have the following backup
strategy:
6 incrementals (*2)
1 weekly (*2)
1 yearly (*1)
Currently,
$Conf{FullKeepCnt} = [ 1, 0, 1, 0, 0, 1 ];
I know this isn't right, but it's not what I would anticipate seeing. For
instance, one of my backup targets has:
Backup# Type Filled Level Start Date
626 full yes 02/21 23:00
645 full yes 03/15 01:02
649 incr no 13/19 01:00
650 incr no 13/20 01:00
651 incr no 13/21 01:00
652 full yes 03/22 01:00
653 incr no 13/23 01:00
654 incr no 13/24 01:00
655 incr no 13/25 01:00
incrs between 3/16 and 3/18 are missing because of a power outage and the
backuppc filesystem not mounting correctly.
So how should I set up my FullKeepCnt to keep one backup for a year and two
sets of fulls/incrementals for the past two weeks?
Thanks,

The meaning of FullKeepCnt array doubles for each element so if you do
weekly fulls you can't quite hit yearly boundaries.
[2,0,0,0,0,100]
would keep the 2 most recent weeklys and one every 32 weeks for longer
than you are likely to want them. Per
http://sourceforge.net/apps/mediawiki/backuppc/index.php?title=Keep_yearly_backups
the next step would be 64 weeks - but you could keep monthlys to have
the last year boundary like:
[2,0,13,0,0,100]
Note that with backuppc's pooling it doesn't take that much more space
to keep more history unless there is a big turnover in file content.
Also, you may see a few more nearby fulls than you expect since they are
retained if any incrementals depend on them.

There are a lot of threads about this. In my point of view it was one of
the few room for improvements within BackupPC.
I've developed a patch for V3.1 which can be found in backuppc.devel. It
will solve your requirements. But I didn't migrate the patch to V3.2 and I
don't know when I will do that.

Re: [BackupPC-users] backend to nfs nas share
I was planning to make my backend storage box with zfs which as i understand it support easy expansion to multiple new disks. Then run either iSCSI or NFS between the backend storage box and the front end BPC box On 23 March 2011 21:34, hans...@gmail.com wrote: Best to use LVM (over RAID if you like) for future expansion flexibility. I happen to use OpenFiler as a NAS host for the same reason - can act as an iSCSI host as well as all the mainstream filesharing protocols, relatively easy to set up compared to building your own from a generic distro. Note it is not recommended to run BPC on the OF host itself, best to treat OF as a black box appliance. On Tue, Mar 22, 2011 at 7:52 PM, Jeffrey J.

I was looking at using an NFS share and connecting backuppc to the NFS share. As I understand it NFS has no real limit on the filesystem size other than that of the hosting machines filesystem limits, but does backuppc have any filesystem requirements or filesystem size limits? I noticed the inode issue mentioned in documentation, im looking into that one currently for NFS. I saw the limits about individual file size in the faq but im more concerned with the overall filesystem backuppc is running on top of. BackupPC itself has no such limits. The limits are based on the filesystem where TopDir is located. Also, btw, the issue is not NFS but the filesystem that NFS is mounting from the remote machine. So you need to look on the remote machine filesystem partition and see how much space and inodes are available. -- Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.

[BackupPC-users] mysql addon or plugin?
I have seen some examples of using a local backup script to dumpmysql to a local dir, then backup that local dir via BPC, but i was hoping for something a little more robust. I was looking into replacing the tar commands that pipe back to ssh with a mysqldump command so it pipes one big sqldump file into BPC, and ive been looking at the local script method but neither seems very robust. I was hoping maybe there was like a plugin or something that would create an extra backup method or something like that. preferrably i was hoping to be able to backup individual databases as individual files. Is there any current methods for this ? Thank you Lawrence -- Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
