4ae138d9-ebc1-4e9d-923b-02b9a6d6bd35 Posted May 14, 2016 Report Share Posted May 14, 2016 I have noticed that my backup logs recently have said at the beginning "using thorough rebuild." That sounds like more than is needed on a daily basis. Daily backups can be many gigabytes and take a long time. I don't remember seeing that in the past, and I can't find anything in the documentation about it. I have had to make recycle backups for both of my backup sets recently, so I don't have records showing if backups have always used thorough rebuild or if that is something new. What does it mean to use a thorough rebuild for every normal backup? Is it desirable? Is there a way to choose a different option? I am using Retrospect Desktop for Windows, version 11.

Lennart_T Posted May 14, 2016 Report Share Posted May 14, 2016 My guess is that you turned off "Fast catalog rebuild" in the Backup Set properties and the message you see in the log is just a reminder. It would be interesting to see a full log from a backup (minus JUST the user name and other personal information). Quote Link to comment Share on other sites More sharing options...
Scillonian Posted May 14, 2016 Report Share Posted May 14, 2016 "Using thorough rebuild" started appearing in backup logs with Retrospect 11 for Windows. I believe this is related to the changes made to Catalog rebuilding in Retrospect 11 for Windows and also the .session files that Retrospect 11 for Windows stores with a disk backup set's .rdb files. The .session files and the changes they relate to are covered in post ".session" files stored alongside ".rdb" files new to Retrospect v13? on the 'Retrospect 9 or higher for Macintosh' board. It would be interesting to see a full log from a backup (minus JUST the user name and other personal information).

Lennart_T Posted May 14, 2016 Report Share Posted May 14, 2016 This is where 'Using thorough rebuild' appears in the log from Retrospect 11 for Windows backup: Thank you. As I thought: Just a piece of information. It doesn't take any execution time Quote Link to comment Share on other sites More sharing options...
4ae138d9-ebc1-4e9d-923b-02b9a6d6bd35 Posted May 14, 2016 Author Report Share Posted May 14, 2016 Yes, it seems that Fast Rebuild is obsolete with the latest version. There doesn't seem to be an alternative to thorough rebuild, but apparently it doesn't affect performance. Thanks for your suggestions.
