What is sector size in SQL Server database?
SQL Server supports disk drives that have standard native sector sizes of 512 bytes and 4 KB.
How do I find my hard drive sector size?
This answer is severely outdated.
- Run msinfo32 in command line that should popup a GUI window called “System Information”
- In the left pane select “System Summary->Components->Storage->Disks”. This should load info of all drives in the right pane.
- Find your desired drive and check the value for “Bytes/Sector”.
How do I change disk sector size?
Splendid. You can’t change the sector size of a hard drive – the sectors are created when the hard drive is manufactured and can’t be changed. You can change the NTFS cluster size (also called the “allocation unit size”) of the file system using Disk Manager as shown by nikorr, but you have to reformat to do it.
How big will the transaction log backup be?
– Database Administrators Stack Exchange How large will the Transaction Log backup be? I encountered a production database of 12 GB with a log of 90 GB. Full and differential database backups are made with a third-party backup tool, but no one is backing up the transaction log so it got way out of hand in the past year.
How big is a SQL Server transaction log?
We use SQL Server 2012 (SP2) running in Full recovery mode. We take half-hourly transaction log backups. Our DB size is 20GB. Every night we perform DB maintenance tasks – full backup, rebuilding some indexes, update statistics, clearing some old data. The half-hourly transaction log backups save to an external HDD.
Is the LDF file size the same after a database backup?
Even when you create a transaction log backup, the size of the online transaction log will remain the same. When restoring a database from a full database backup, the LDF file size will remain the same as in the original one, though it’s nearly empty.
How to reduce the size of a transaction log file?
For information, see Factors that can delay log truncation. Shrinking a log file removes one or more VLFs that hold no part of the logical log (that is, inactive VLFs). When a transaction log file is shrunk, inactive VLFs are removed from the end of the log file to reduce the log to approximately the target size.
