Not sure if it’s the right mailing list as this is my first post. I have a ubuntu Server: Ubuntu 9.1 Server Edition – No GUI I normally do a full backup of my ubuntu webserver (/var/www/) using a cronjob and tar | gzip , The backup is about 1.23GB in size everyday.. Since we’ll be putting more stuff on this webserver, a full backup everyday is a little bit over the top, so I would like to start using incremental backups in order to save space. Problem is Im not too familiar with incremental backups. My thought is to use tar with mtime 1. But I am not sure how to handle the rest. Any of you are used to work with incremental backups? I plan to do a Full Backp every week, then incremental on week-days. </div></div></blockquote>I use <a href="http://backuppc.sourceforge.net/faq/BackupPC.html">backuppc</a> to do that, and I like it. It can be used to backup your system, or just to backup your databases daily backups (Am I making sense to you?) <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div link="blue" vlink="purple" lang="EN-US"><div> Last Question about the restore.. Scenario: We’re Thursday, and I want to do a restore.. The Full backup was taken on Monday, but incremental were taken every nights.. I Only have to restore the Full Backup and the incremental backup from last night? </div></div></blockquote><div>backuppc handles this matter different. In "classical" backups, the answer depends on the incremental backup level. An incremental of level N stores the differents against the existent backup with "higher less than N" level (and you may think of a full backup as the level 0) To simplify, if you made the full on Monday, then a level 1 on Tue, a level 2 on Wed, you'll have to restore them all in that order But if you made the full on Monday, then a level 3 on Tue, a level 2 on Wed, you'll have to restore the full and only the level 2 incremental of Wed only (level 2 was made against the full, not against the Tue level 3) If that's what you were asking for, you may take a look (forget the dump command, just look at the explanation on levels) at <a href="http://surf.ap.seikei.ac.jp/%7Enakano/dump-restore/dump-restore-mini-HOWTO.en.html#ss4.1">http://surf.ap.seikei.ac.jp/~nakano/dump-restore/dump-restore-mini-HOWTO.en.html#ss4.1</a> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div link="blue" vlink="purple" lang="EN-US"><div> Regards </div> </div> -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>
