Description: Checking the Barracuda Appliance web console and it shows an error or alert for low disk space
Common customer description: I keep getting email notifications for low disk space
Probing questions: When did you start receiving these emails?
Steps to resolve:
1. Open a web browser
2. Connect to the Barracuda Web Console by using login credentials
3. If they have high Disk storage, you will find it on the main status page
- In the middle pane called Backup Statistics
- The disk status goes like this:
0-60% = Green status (enough storage)
70-80% = Orange status (getting high on storage but will still work)
90-100% = Red status (storage is practically maxed out, it may or may not backup up anymore)
4. If the status is around the orange or red mark, we need to figure out what is taking out the most space on the drives
- To do that, go to Reports>>Large Items
- It will generate the list of all the items the disk has and how big they are
5. In this case, there is nothing to do since the SQL Database is taking up majority of the space. So, we cannot change the selections of the database.
6. Going with this example, what if we cannot remove any files? The next thing to look at is the retention policies
- Go to Backup>>Retention Policies
- It will put you to a main page that will look like this
7. Normally, you don’t want to mess with the retention policies unless we necessarily have to. The settings that they have might have a reason for it (need to keep certain files for awhile)
8. If the policies were changed, it will take 24 hours for it to fully accept the new changes (a built in safe measure in case you actually do need the file and you can quickly get the file or change the policies again)
- Once the 24-hour period is over, the Barracuda device will purge (remove) the selections that is not under the new retention policy and once that happens the files cannot be recovered
9. Watch the backups for a few days to a week to make sure that they backups complete successfully and there isn’t any more issues
Additional considerations: Disk Full alerts can be tricky to solve. It might require removing files from selection or changing the retention policies.
