So I have some databases ( 3 ) and they're not big. every Differential backup has like 50mb and then we have a full at midnight.



Is there a problem doing this?



I could make the full backup then logs, then diffs like 4 or 5 times a day, but storage is not a problem with this instance.

          Storage is not why you take log backups. You take log backups when the database is in full recovery model, and you need point-in-time recovery between full or incremental backups.



          If your business can afford only 1 hour of lost data, then I'd typically setup nightly full backups for smaller databases, with log backups every 30 minutes during business hours (or even 24-hours per day).



          If you have the database in simple recovery model, and each database is only a couple of hundred megabytes, you could simple take full backups every hour, or half hour.



          Essentially, the decision comes down to answering these questions:




          1. What is my recovery point objective?

          2. What is my recovery time objective?


          See Wikipedia for great details about what those two things actually mean.



          If you're storing high-value, business-critical data in those databases, you should understand log backups, and the transaction log and recovery in general, to avoid being in a situation where you're unexpectedly missing data, or down for an extended period of time.

          • Hey thanks Max. But that's my question. I can lost 1 hr of data. thats no problem, that's why I'm creating all of them diffs ( I'm using full recovery mode ). Then I can restore only the ful + diff , instead of full + log + log + log + log + log + log + log + diff..
