This will create a series of directories called daily.0 through daily.13
weekly.0 to weekly.3 ... etc.
=Another example of rsnapshot configuration on amahi 5.1=
In this example automated backups are made to an external usb drive.
Plug in the USB drive, it wil probably mount automatically under /media/yourdisklabel
First login as root in a terminal (putty or ssh root@hda)
and type
:mount
in the output, find which device is your usbdrive, possibly /dev/sdb1
=Format usb disk=
You need to format the disk for rsnapshot to be able to use hard links. FAT formatting does not support this unfortunately.
:Umount /media/yourdisklabel
:mkfs -t ext3 -v -L usbdisk /dev/sdb1
THIS WILL ERASE ALL DATA ON /dev/sdb1, MAKE SURE THIS IS YOUR USB DRIVE AND NOT ANOTHER DRIVE
=Install rsnapshot=
:yum install rsnapshot
:mkdir -p /media/usbdisk/.private/.snapshots
:chmod 0700 /media/usbdisk/.private/
:chmod 0755 /media/usbdisk/.private/.snapshots/
=Mount your usbdisk permanently=
To Mount your usbdisk permanently (so the backup will work after a reboot) do the following:
:cp /etc/fstab /etc/fstab_bak
:nano /etc/fstab
Add to this file
:LABEL=usbdisk /media/usbdisk ext3 defaults 0 0
Save the file.
=Modify rsnapshot configuration=
:nano /etc/rsnapshot.conf
make the following modifications to the file rsnapshot.conf
for blank spaces use TABS!
:snapshot_root /media/usbdisk/.private/.snapshots/
:no_create_root 1
:interval hourly 6
:interval daily 7
:interval weekly 4
:interval monthly 12
:verbose 3
:backup /var/hda/files/docs/ localhost/
:backup /var/hda/files/pictures/ localhost/
:backup /var/hda/files/movies/ localhost/
:backup /var/hda/files/music/ localhost/
:backup /var/hda/files/othersharesyoumade localhost/
Save the file
:rsnapshot configtest
this should return: syntax OK
=Email reporting=
for email reporting on your backups:
:cp /usr/share/doc/rsnapshot*/utils/rsnapreport.pl /root
:chmod 744 rsnapreport.pl
=Automate backup with cronjob=
:crontab -l > cronjobs
:nano cronjobs
add to this file for running rsnapshot and a weekly email report on rsnapshot:
:0 */4 * * * /usr/bin/rsnapshot hourly 2>&1 | /root/rsnapreport.pl > /root/rsnapreport
:30 23 * * * /usr/bin/rsnapshot daily
:00 23 * * 1 /usr/bin/rsnapshot weekly
:30 22 1 * * /usr/bin/rsnapshot monthly
:00 22 * * 6 /usr/bin/rsnapshot du >> /root/rsnapreport | nail –r "somereturnadress@provider.com" -s"HDA backup report" -S smtp=smtp.yourprovider.com youremail@provider.com < /root/rsnapreport
Save the file
:crontab cronjobs
Rsnapshot should now be operational.
=Make your backups available on clients (READ ONLY)=
If you want to make the backups accesible from your clients:
Create a //hda/backup share in the HDA webinterface
:chkconfig nfs --level 2345 on
add a read only NFS export:
:nano /etc/exports
add
:/media/usbdisk/.private/.snapshots/ 127.0.0.1(ro,no_root_squash)
Save file
Unfortunately mounting an NFS share in fstab did not work on my machine after a reboot, so I chose an alternative configuration that mounts the share later in the booting process:
:nano /etc/rc.local
Add
:mount -r -t nfs localhost:/media/usbdisk/.private/.snapshots/ /var/hda/files/backup/
save file
