I am about to write my first shell script for backing up my server.
These are the steps I have identified so far.
- Copy files to be backed up to /srv/backup/
- run mysqldump and copy the file to srv/backup/databases
- run duplicity to backup /srv/backup/* to another folder on my machine
I am writing a bash shell scrip that will be run everyday, and will carry out the three tasks mentioned above.
Note: point 3 (backing up to a local folder) is only a temporary measure - to allow me to understand what I'm doing, since all the tools I am using, are new to me. Once I can backup and restore correctly, I will use duplicity to compress and encrypt the files and upload them offsite.
If my understanding of duplicity is correct (according to the documentation here), the first time I run the script, a FULL backup will be done. Every subsequent backup will then be incremental. I will then force a FULL back on say a weekend.
First things first though - I have a few questions:
I would like to use backup rotation for the 'scheme' described above - I would like some recommendations on what kind/type of rotation to use.
Once I have implemented the backup rotation, how can I restore from a particular day back in time (assuming the backup exists of course). ?
I am running Ubuntu 10.0.4

Some websites have essential tasks in the crontab file. So perhaps you need to throw a line like "crontab -l > /srv/backup/my-crontab" into the script. – David Cary – 2014-02-04T18:23:55.680
