Hello all, I'm getting ready to start using Amanda as a backup solution. To prepare, I've read the online documentation and I've also read a section in the Red Hat Linux Bible. I also read through the FAQ's. I am a bit confused with some items. Mainly the configuration. The amanda comes with the DailySet1 as an example.
Is it possibly to only use 1 configuration (eg DailySet1) to accomplish both the full and the incremental backups? From past experiences with other backup utilites, one would create and schedule both full and incremental's (as does the Red Hat Bible's example). The thing that further confuses me is how to define an incremental. The backup for the full is easy enough in the disklist file to call the 'always-full' definition. Where I'm confused is which types are for the incremental. From what I've read some of the attributes it looks as if it can figure this out with the following settings. The following is from the example amanda.conf file. I've added what I think I want to accomplish as well: dumpcycle 4 weeks # the number of days in the normal dump cycle I'm planning a weekly cycle: Every Friday a full backup so I'm assuming it would be: dumpcycle 1 week runspercycle 4 weeks # the number of amdump runs in dumpcycle days Now I'm planning on doing incrementals from Monday - Thursday and a full on Friday: runspercycle 5 days ??? tapecycle 25 tapes # the number of tapes in rotation # 4 weeks (dumpcycle) times 5 tapes per week (just # the weekdays) plus a few to handle errors that # need amflush and so we do not overwrite the full # backups performed at the beginning of the previous # cycle I understand I have to figure out what my capacity requirements are. If one configuration for the full and one for the incrementals are needed I'd be interested in how these are configured... I'm also looking for advice on recommendations for single tape drives for linux as well as media types. I don't want to further complicate my introduction with additional configuration issues. Thanks for the help in advance James RHCE
