Backup Policy

Posted on 2011-05-05

I am setting up a backup policy for a company, and they have about 100GB of data.
I went LTO3 tape, and i have setup a full backup for every friday night, and incrementals every day of the week until friday morning, when they will insert a new tape. We will rotate these 2 tapes to have at least 1 week of backup stored on tape. Quarterly we will use a different tape and store it offsite with a full backup. Data doesnt really change too much on a daily basis. Any critiques?

    I don't notice any part in there about regularly testing your backups.  Perhaps it's just assumed.  But all the backup planning in the world doesn't matter a lick if you don't make sure what you're backing up is actually restoreable, regularly.

    Im not really a big fan of incremental backups. I would prefer differentials as in my expeirenc that are more easily restorable. With an LTO 3 drive with a capacity of 400/800gb you should easily be able to fit monday-thursday differentials and a Friday full on the same tape.

    Adam, yes i will be testing, great point :)

    xxdcmast, good point, so when doing a restore, i just need the last full backup and the last differential right?

    in my opinion (and many other, if articles are to be believed), tapes fail on a frighteningly frequent regularity.

    two enterprise class, rotating on a weekly basis, doing incremental backups everyday, and a full backup once a week is good.
    and quarterly, you can buy a new hard drive (a home hard drive) and store it offsite.

    If you do the 4 diffs and a full then in the event of a failure you are correct you would need the last full and the last diff to restore.

    This isnt so much of a big deal if your tapes can hold multiple backups before being filled but becomes more of an issue when you have backups that span tapes and you need to find all your incrementals to restore.
