I am intermediate in database admin. Please give me your solution for this issue.
Size of my db is growing about 5M every 2 weeks. Now its size is 118G. my db is in full recovery mode, and I do not have log backup.
Is this a good solution?

1- Perform a full backup
2- execute checkpoint
3-Perform full Backup
4- Perform transactional log backup
5- shrink log file type
6- schedule transactional log backup

Also, can I do these processes during users are connected ?

Skip steps 2 and 3. Move step 6 to the new step 1.

And if your log file is truly too big then do step 5.

So the new order would be:
1. Create tlog backup schedule
2. Perform Full backup
3. Shrink log file if too large.

Doing this will allow the schedule to take care of the tlog backups.

I would say, do full backup weekly, daily differential and hourly log backups based on the RTO provided.

If your database is in full recovery model, then definitely, you need to do log backup to truncate the logs.

An RTO was not provided. And your suggestion has more to do with RPO and not RTO. Though neither has been specified so they are both unknowns.

Thanks for the correction, however, I thought RPO(Recovery Point Objective) and RTO(Recovery Time Objective) are basically same? Please let me know.

RPO, how close to the time of failure do you need to recover. Or, how much data are you willing to lose time wise. Can your people manually recover the last one hour of work for example.

RTO, how long it will take to restore operation.

Cool

They can be radically different.

For example, I worked with a card processing company a few years back, their RTO was minutes. Literally, every minute they were down they were losing money because they couldn't process transactions. Their RPO however was 48 hours. They could lose up to 2 days of data without concern because they got summaries from the banks every 24 hours containing the previous 2 days of data, which they could use to recreate any lost transactions in their systems.

Hi,
Thanks for your answer. I did this solution on my test server and it worked, but I am worry! Can I do that on my production server during the users are connected and they work with application?
Also, we donot have lots of transaction daily.So, I want to schedule one full backup daily, and one transactional backup every one hour. Now for providing transactional backup which method is good? append or overwrite
I appreciate your answer in advance!
