The database administrator is typically responsible for the restoration of a SQL server backup set whenever you lose files or whole folders from your compromised SQL server database due to logical failure or physical damage. The backups should be restored in a meaningful and logically correct sequence or else they won’t work. This is the proper way of dealing with sql server data recovery. SQL Server restoration and recovery supports data restore from whole database backups, a data page, or a file. In other words, the best way to go about data recovery of your SQL database is to have a running backup of it so that when it fails, you can do a complete database restoration with little to no problem. You’ll have the server offline during the duration of the recovery.That’s the nitty-gritty of sql server data recovery.
What to Expect
- When undergoing a complete database restoration operation, you should have the database offline. It will go up online only after everything is back in working order. Meanwhile, file restoration requires recovery and restoration of a data file or a set of them. While they’re being restored, the file groups that have the files are automatically rendered offline while the operation is going on. When you access the offline file or file group, you’ll instead get an error until the operation is complete.
- When it comes to restoring a page, the full recovery or bulk logged recovery model allow for individual database restoration. Regardless of the number of file groups involved, you can perform page restoration on any of the databases that have been compromised. Of course, this is reserved for servers with backup. In regards to getting lost files or inaccessible servers with logical errors (as well as servers that have been hacked and destroyed), you need a different type of app or software to do the job.
- Please be aware that prevention is better than the cure. In turn, an SQL server backup system that supports all sorts of operating systems (under Hardware and Software Requirements) is much better than attempting to retrieve files from an already inaccessible or compromised server full of corrupted files and damaged storage media. In particular, the former supports complete system or database restoration that has recently (and automatically) been saved by the software.
In contrast, an SQL server undelete or retrieval app for something that’s already destroyed will leave you picking up the pieces of a virtual pot, never to be glued back together again because certain parts of the pot have been smashed into powdered dust and bytes. It’s better to have a redundant copy of what’s contained within your SQL server so that in the event of a hack attack or a serious logical error that renders the server itself inaccessible, you can rebuild everything from the ground up.
