Useful scripts

[Rusky]

I just setup a cron job to create nightly backups of my configuration, pretty handy.

Any other cool scripts you guys have come across that you'd care to share?

I have a nightly cron job that backs up the configuration to a file with the date in the name. Over time this has naturally created a lot of redundant files, so I hacked together this bash script which will only backup the configuration if it is different than the newest file in the bkpfolder.

Code:

#!/bin/sh
bkpfolder='/mnt/tank/bkpconfig'

fc="`find $bkpfolder -maxdepth 1 -type f | wc -l | tr -d '[:space:]'`"
if [ $fc -eq 0 ]
then
  cp /data/freenas-v1.db $bkpfolder/`date +%Y%m%d`.db
else
  find $bkpfolder -maxdepth 1 -type f -exec stat -f "%m%t%N" {} + | sort | tail -1 | cut -f 2 | xargs cmp /data/freenas-v1.db
  if [ $? -ne 0 ]
  then
	cp /data/freenas-v1.db $bkpfolder/`date +%Y%m%d`.db
  fi
fi

...except that the system does this automatically for you, and has for a few releases now.

That's cool, where are these backups stored?

/var/db/system/configs-longhexnumber. On my system it's /var/db/system/configs-03dfc785c4b1491e8f0739ff94ed3f4b.
