Question regarding vertica hard link backup
What happens when I create hardlink local backup and data is changed in a database. Due to that, basically some database files are changed/modified.
But doesn't this change the file for hardlink backup also..?
- I create hardlink local backup named "hb1"
- Update 100 rows in a table and commit
- Due to P2, the specific file (let's say inode=100) has been modified.
- Hardlink local backup "hb1" now basically contains data for inode=100 from P3
How can I restore my database back to P1 ( I mean how does it work) ?
