TIR with move detection

Hi,

I need a clear idea of True Image Restore with move detection

Regard's

  • OK - let me try ...

    Normal backups do the following ..

    Monday - files A, B and C are backed up in a full backup

    Tuesday - file D is created and gets backed up by the incremental backup

    Wednesday - file A is deleted - nothing new to backup

    Thursday - File C gets moved to a different directory - gets backed up as considered a new file

    Friday - server breaks - So you restore it all from full and incremental backups - when done you have restored file A, B and C from the full, D from the incr, C to a second location.

    So you server doesnt really look like it did when it broke - you have a file back on it that was deleted plus one file in two locations.

    So if you use TIR with Move detection you get the following:

    Monday - files A, B and C are backed up and the TIR mapping taken

    Tuesday - File D is backed up and a new TIR mapping taken

    Wednesday - nothing to back up but new TIR mapping taken

    Thursday - Nothing backed up as TIR realises that the file has just moved - new TIR mapping taken.

    Friday - When you run the restore it looks at the latest TIR mapping so this time when you do the restores you get B, C only once in the latest location and D.

    So now your server looks exactly like it did when it was last backed up

    Does that make any sense?
