after really long time of non writing here; finally I’m happy to announce a small handy pre backup script hook for DA (Directadmin) server control panel system.

The idea behind is to check free disk space (in percents) of a particular partition, before (previously to) DA will fire up it’s backup script. This will work for user backups along with admin level backups.

For many years I found that I always face the problem that the local backups are eating up all the disk space on the server hence a nice (per user/account) pre backup free disk space will save you later problems with 100% disk full.

DA has a wonderful feature for calling pre/post scripts for various functions in the system, which one of them is the built-in backup system.

According to the DA knowledge base  documentation (and with John’s advice), we need simply create a bash/shell script called ‘user_backup_pre.sh’ and put it exactly here:

/usr/local/directadmin/scripts/custom/user_backup_pre.sh

DA knows that if such files exists in this path with this name, it should first run it and receive a NULL (false) response, otherwise it will not continue with the backup process.

I modified their ‘highload’ checker example script and created this one:

#!/bin/sh
PARTITION=/dev/sda1
MAXUSED=90

checkfree()
{
DISKUSED=`df -P $PARTITION | awk ‘{print $5}’ | grep % | cut -d% -f1`
echo “$DISKUSED < $MAXUSED” | bc
}
if [ `checkfree` -eq 0 ]; then
echo “$PARTITION disk usage is above $MAXUSED% Aborting back
up.”;
exit 1;
fi
exit 0;

Just set your maximum allowed used disk space variable MAXUSED (the value is in percents, just exactly the value you get with the df command in the USE% column).

Then the subject PARTITION (if you have separate /home partition then set it to, since, as you know, DA stores his admin_backups at /home/admin/admin_backups/ path). In my example it’s /dev/sda1 because this server uses single partition for everything.

Finally chmod this script to 755

chmod 755 /usr/local/directadmin/scripts/custom/user_backup_pre.sh

Find your biggest user and make sure that the maximum disk usage will be kept below his size.

Direct download user_backup_pre.sh

New syncing module and fixed indexes.

The mirror is moved to an Apache web server from Lighttpd for  better compliance of Debian clients.

I’ve precompiled a Lighttpd 1.2.28 Debian’s version with mod_h264 (version 2) streaming module support on Squeeze amd64 system.

Ready for use, grab from here

Usage (lighttpd.conf):

server.modules = (
“mod_access”,
“mod_alias”,
“mod_compress”,
“mod_redirect”,
#       “mod_rewrite”,
  “mod_h264_streaming”,
)
h264-streaming.extensions = ( “.mp4″ )

Tested on Debian Squeeze, using it on production system.

Packages mirror is ready and might be used.

While the disk utilization (checked by iostat) is around 81-90% only.

To set ‘writev’ on lighttpd, edit lighttpd.conf and put this:

server.network-backend = “writev”

again this might not help everybody, but it worth a test.

This mirror synced twice a day and contains all Centos Packages and ISOs.

For instance you don’t want to show the dir-generator-plus.php file and the included folder images directory; I also include footers sometimes so i prefer to them as well.

download it dir-generator-plus.php

The usage is simple, edit your lighttpd.conf file at the host area:

dir-listing.activate = "enable"

index-file.names = ( "/dir-generator.php" )
for more info about the usage of Lighttpd dir listing please visit the lighttpd wiki
