Development of and creating tarbackup
This is a spot where I can put stuff that was going to go in the wiki but was changed so is no longer useful to the project.
None of this information pertains to tarbackup and is deprecated (NOT USED). This is for archival purposes only.
Well, I tried FreeBSD 9.0 with ZFS as the root and it failed to boot after an interrupted (CTRL+ALT+DEL) boot. The error message on boot is "can't exec getty '/usr/libexec/getty/' for port /dev/ttyv0 \n No such file or directory" I'm trying CentOS 6.3 with mdadm and a RAID6 with regular scrubbing for fault tolerance. It won't give me the end-to-end data garauntees of the ZFS, but at least I'll have something up and running.
upload your data to tarbackup
curl -u username:password -i -o /tmp/output.txt -T /tmp/example.txt 'http://tarbackup.com/put.php'
Download your data from tarbackup.com via wget
wget --user=yourusername --password='yourPassword' http://tarbackup.com/fullbackup.tar.gz.enc
Where the data is hosted
- On a box running FreeBSD 9.0 To test this system on a virtual machine, I'm using:
- 3 virtual hard drives of 4GB per drive
- 3 storage drives of 500MB per drive
- 1536 MB of allocated memory for the virtual system
Follow these steps to make your own:
download the FreeBSD 9.0 ISO installation CD; http://www.freebsd.org/where.html
(referenced from: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ2 and http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ2)
At the install prompt, choose "Shell", then type:
gpart create -s gpt ada0
gpart create -s gpt ada1
gpart create -s gpt ada2
gpart add -s 64K -t freebsd-boot -l boot0 ada0
gpart add -s 64K -t freebsd-boot -l boot1 ada1
gpart add -s 64K -t freebsd-boot -l boot2 ada2
gpart add -s 512M -t freebsd-swap -l swap0 ada0
gpart add -s 512M -t freebsd-swap -l swap1 ada1
gpart add -s 512M -t freebsd-swap -l swap2 ada2
gpart add -t freebsd-zfs -l disk0 ada0
gpart add -t freebsd-zfs -l disk1 ada1
gpart add -t freebsd-zfs -l disk2 ada2
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada2
zpool create -o altroot=/mnt zroot raidz2 /dev/gpt/disk0 /dev/gpt/disk1 /dev/gpt/disk2
zpool list
zfs create zroot/tmp
chmod 1777 /mnt/tmp
zfs create zroot/usr
zfs create zroot/var
zfs create zroot/home
exit
continue the install; when the installer asks about partitions, choose shell and type:
exit
after install is finished, reboot and then boot to shell from Live CD on the next boot
echo 'zfs_enable="YES"' >> /mnt/etc/rc.conf
echo 'zfs_load="YES"' >> /mnt/boot/loader.conf
echo 'vfs.root.mountfrom="zfs:zroot"' >> /mnt/boot/loader.conf
zfs unmount -a
zpool export zroot
zpool import -o cachefile=/tmp/zpool.cache -o altroot=/mnt zroot
zfs set mountpoint=/ zroot
cp /tmp/zpool.cache /mnt/boot/zfs/
zfs unmount -a
zpool set bootfs=zroot zroot
zpool set cachefile= zroot
zfs set mountpoint=legacy zroot
zfs set mountpoint=/tmp zroot/tmp
zfs set mountpoint=/usr zroot/usr
zfs set mountpoint=/var zroot/var
zfs set mountpoint=/home zroot/home
reboot
(after reboot, to create the storage pool)
zpool create data raidz2 ada3 ada4 ada5
(be sure that the directory was properly created and mounted)
cd /data
(list the zpools)
zpool list
installing apache (referenced from: http://www.freebsd.org/doc/handbook/network-apache.html, http://www.cyberciti.biz/faq/freebsd-apache-web-server-tutorial/)
pkg_add -r apache22
echo 'apache22_enable="yes"' >> /etc/rc.conf
configure the /etc/hosts file with the IP of your server, in my case:
echo 'vtarbackup 192.168.2.177' >> /etc/hosts
reboot or service apache22 start or service apache22 restart or /usr/local/etc/rc.d/apache22 restart
pw groupadd targroup
wget --no-check-certificate https://github.com/nanch/tarbackup/zipball/master -O tarbackup.zip
tar -xvzf tarbackup.zip
a new directory nanch-tarbackup-XXXXXXX has been created
pkg_add -r git
git clone git://github.com/nanch/tarbackup/
if you already have partitions on the disk before you start, you can delete them from the install shell with: (referenced from: http://www.wonkity.com/~wblock/docs/html/disksetup.html)
gpart delete -i 1 ada0
gpart delete -i 2 ada0
gpart delete -i 3 ada0
I use nano, which can be installed with pkg_add -r nano and is executed with /usr/local/bin/nano filename

I tried gpg but gave up. I'll keep this for reference:
gpg
to encrypt: gpg -c --output fullbackup.tar.gz.gpg fullbackup.tar.gz
to decrypt: gpg --decrypt fullbackup.tar.gz.gpg > fullbackup.tar.gz
