Backups

February 10, 2007

Well, backups are working. Every night my PowerMac G5 backs its important stuff up to external disks, and then a few hours later rowla.nuxx.net shoves its important bits down to one of the disks. It’d be better if it was all sent offsite, but I do only have a certain amount of space available remotely.

    what software are you using for the backups?

    just like a crontab/rsync thing, or external software?

      /usr/bin/rsync ;)

      Oh, and kicked off by cron at around 3:30am. The script is as follows:

      #!/bin/sh

      PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin

      # If /Volumes/Charlie exists, start backing stuff up to it.
      if [ -d /Volumes/Charlie ]; then
      #echo Found Charlie...
      # Everything on Beta...
      #echo rsync -a --delete --exclude '/.Trashes' --exclude '/.Spotlight-V100' --exclude '/Unison' /Volumes/Beta/. /Volumes/Charlie/Beta/.
      rsync -aq --copy-links --ignore-errors --delete --exclude '/.Trashes' --exclude '/.Spotlight-V100' --exclude '/Unison' /Volumes/Beta/. /Volumes/Charlie/Beta/.

      # ~c0nsumer, except for ~/Music
      #echo rsync -a --delete --exclude '/Music/*' /Users/c0nsumer/. /Volumes/Charlie/c0nsumerHome/.
      rsync -aq --copy-links --ignore-errors --delete --exclude '/Music/*' --exclude '/Library/Application Support/Unison' /Users/c0nsumer/. /Volumes/Charlie/c0nsumerHome/.
      fi

      # If /Volumes/Delta exists, back more stuff up to it.
      if [ -d /Volumes/Delta ]; then
      #echo Found Delta...
      # ~c0nsumer/Music
      #echo rsync -a --delete /Users/c0nsumer/Music/. /Volumes/Delta/Music/.
      rsync -aq --copy-links --delete /Users/c0nsumer/Music/. /Volumes/Delta/Music/.

      The stuff from remote is just sent down to home.nuxx.net which has port forwards in place to make ssh connections end at the G5.

    On the subject of backups, this is what I use for most of ofdoom.
    Mail and the database get special treatment, so I have the nodump flag set for them.

    #! /bin/sh
LEVEL=$1
DATESTAMP=$(date "+%G.%m.%d")
PIPE=/tmp/aPipe.$$
mkfifo -m 600 ${PIPE}

for SYSTEM in root:/dev/ad0s1a usr:/dev/vinum/usr home:/dev/vinum/home ; do
    MP=$(echo ${SYSTEM} | cut -f1 -d:)
    DEV=$(echo ${SYSTEM} | cut -f2 -d:)
    FILE=${MP}.${DATESTAMP}.level${LEVEL}.dump
    cat ${PIPE} | ssh -2 -C -c blowfish -p 2222 archives@archive_host "cat - > /Users/archives/backups/dumps/${FILE}" &
    /sbin/dump -${LEVEL} -a -C 32 -h 0 -f ${PIPE} -u ${DEV}
    sleep 1
done
rm ${PIPE}%
