1. Get initial IP from local wiki log

1. Restart the peer

sub restart { logAdd "$daemon is restarting using: $::cmd"; killChildren(); exec "sleep 1; $::cmd"; }

1. Kill all processes related to this peer

1. Backup the server image
2. - this backup can be unpacked over a minimal debian install, or even over our VPS's default redhat install
3. - use [[Debian Conversion]] notes for unpacking process

1. Backup wiki database

1. Transfer the days backup over SSH using SCP

sub scpBackups { my $lpf = shift; if ($#_>0) { spawn 'scpBackups', $lpf, $_ for @_ } else { my $domain = shift; my $name = $lpf.'-wiki-db-'.strftime("%Y-%m-%d", localtime).'.t7z'; my $lp = lc $::peer; logAdd "scp ../$name $lp\@$domain:/home/$lp"; my $scp = new Net::SCP::Expect( host => $domain, user => $lp, password => $::pwd1, auto_yes => 1, preserve => 1 ); $scp->scp("../$name", "/home/$lp"); my $comment = "$name transferred to $domain"; wikiPageAppend($::wiki, $::wikilog, "\n*".localtime()." : $comment", $comment); } logAdd "Exit."; }

1. Clear sandbox
