Did any body tried using rsync to replicate between backup and primary
qmail servers. Is it recommended for a Qmail hosting multiple domains
having more then 7000 users.
I back up our mysql db hourly with mysqldump, on 24 hour x 7day basis and
with rsync I do it on all servers regardless of how many users they
have, we also do it on a rolling 7 day basis
Pretty simple, you can expend on this greatly like I do in my main
scripts by using logging, timeouts and alarms
but starting point would be:
#!/usr/bin/perl
@weekDays = qw(Sun Mon Tue Wed Thu Fri Sat);
($second, $minute, $hour, $dayOfMonth, $month, $yearOffset, $dayOfWeek,
$dayOfYear, $daylightSavings) = localtime();
$dayOfWeek = $dayOfWeek - '1';
$TODAYIS = "$weekDays[$dayOfWeek]";
$RSYNCP = "/usr/local/bin/rsync -vazH --stats
--password-file=/etc/rsync.secret --delete --delete-after
/home/vpopmail/domains [EMAIL PROTECTED]::vpop-$TODAYIS";
system("$RSYNCP") ;
....
/etc/rsyncd.conf
[vpop-Sun]
path = /backups/machine-or-mailstore_name/vpopmail/sun
auth users = backupuser
secrets file = /etc/rsyncd.secrets
max connections = 50
hosts allow = 203.h.i.dd.en
uid = 0
gid = 0
list = no
read only = no
...just repeat that block for all 7 days changing /sun to what_ever_day
Theres probably better ways of doing it, but this way has worked for me
for years.
