right!

No. I believe I would get one Backup every 4 weeks. 48 weeks each year. I
lost exactly 4 weeks ;-) Therefore 13 would be the correct number ;-)

? should be $Conf{FullKeepCnt} = [4, 0, 12, 0, 100]; for 100 backups every
16 month.

If I use:
$Conf{FullPeriod} = 7,6;# calculated as 365/12/4
$Conf{FullKeepCnt} = [4, 0, 12, 100];
I should get the weekly backups after 8, 15, 23 and 30 (exactly 30,4) days.
and I should get the monthly backups after 30, 61, 91, 122, 152, 182, 213,
243, 274, 304, 334 and 365 days.
And
$Conf{FullPeriod} = 7,61; # calculated from (365*4+1)/4/12/4
should respect also the leap year.
But to get a yearly backup every last or first week in a year is a
challenge, isn't it ?
Could /etc/cron.monthly provide a solution ?

[BackupPC-users] How do I setup OpenSSH - Here is a script which can do this
Hello, I compile the steps, described in http://backuppc.sourceforge.net/faq/ssh.html#how_do_i_setup_openssh into a bash script called "BackupPC_accessSSH". Hope it is usefully for other Backuppc User. It has to run as user backuppc. Therefore it needs execute-rights for at least the backuppc user. WETHER: chown backuppc:backuppc BackupPC_accessSSH chmod u=rwx,og-rwx BackupPC_accessSSH OR: chmod o=rwx BackupPC_accessSSH Maybee the developers decide to integrate this script into the backuppc package. with best regards Matthias -- Don't Panic BackupPC_accessSSH Description: application/shellscript - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Suppose that the Full Period is set to 6.97 as the default install set
it. Let's just call this 7.
Then $Conf{FullKeepCnt} = [4, 0, 12, 0, 0, 100];
will do something close to what you want. You will get 1 Backup per
week for 4 weeks, then 1 backup per month for 12 months (one full per
month till the end of the year) and then you will get 100 (this just
should be a big number) backups that are every 7-8 months, which is as
close to yearly as you can get without skipping any years. You could
add another 0 before the 100 and it would keep a backup about every 15
months or so, which would skip years from time to time. To make it more
exactly to years, you can play with $Conf{FullPeriod}. Hope this helps!

Sorry for replying to my own thread, but one more thought I had: I think the web interface should generate an error for a user that tries to put values in "New Key" that aren't listed as a share name (Such as the variable RsyncShareName if rsync in the transport method). Since my RsyncShareName = '/', it shouldn't allow me to list '/tmp' as a "New Key", as an example. If this had given me an error, I might have figured out what was going on, and at least wouldn't have been trying to backup NCSU's entire distributed file system (gobs and gobs of terrabytes onto my tiny 160 GB HD :)) Thanks again! -- Randy Barlow http://electronsweatshop.com But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.

[BackupPC-users] The web interface may be confusing for BackupFilesExclude
I noticed that I have a ton of errors on the backup of my laptop of a folder that I thought I had in the BackupFilesExclude, and it turns out that I had simply misinterpreted the Web Interface. I had used the New Key: part to put in the paths I didn't want to backup, rather then putting the share name there and then next to it putting the paths in that share that I didn't want to backup. I see how it works now, but it wasn't completely intuitive to me, and I honestly didn't figure out the problem until I took a look at /etc/BackupPC/config.pl and had a big "Aha!" moment :) Not sure what I would suggest to improve it though, except perhaps to use different language. Perhaps say "Share Name" instead of "New Key" and in the boxed that appear next to the share names, some kind of label like "Paths relative to share to be excluded" (maybe that's too long...) so it's more clear? I love BackupPC and I recommend it to all my friends, thanks for the killer F/OSS app! -- Randy Barlow http://electronsweatshop.com But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.
