How to make your Domino backups faster

The newly released Domino V12 includes the Domino Backup component as one of it's new features. Defrag.NSF V12 has also been released as a V12 companion including integration with the new Domino Backup feature, so we thought it would be a great time to look at what happens when you back up fragmented files.

The issues caused by fragmentation (In a physical or virtualized environment) have an insidiously bad impact on the Domino server's overall performance, the O/S and also backups. For the Windows O/S to work with these fragmented files it has to issue more I/O requests to access these files. This results in Split I/O's where unnecessary multiple I/O requests are generated to access the many fragments of each file and this contributes to I/O bottlenecks resulting in some requests being blocked while other are fulfilled. Here we look at the difference we see when backing up fragmented nsf files compared to nsf files that have been maintained by Defrag.NSF.

In a nutshell, here is the difference from our tests depicted graphically, and that is just one database (we have seen production Domino servers full of databases like this). You should maintain not just the databases themselves but also the contiguous free-space required for the DBMT pre-allocation feature to work, Defrag.NSF does all this.

The pics below show the substantial difference in backup stats logged for the exact same database as typically maintained by Defrag.NSF in a contiguous state and also in a typically un-maintained fragmented state.

After the testing completed Defrag.NSF performed it's am scheduled maintenance on the file and returned it to a contiguous state.

Nomad for Web: invalid Cors origin bug on Windows

I've been working on implementing Nomad for Web, and hit an issue where Nomad presents a "Setup Error" when it loads in the browser.

Looking at the SafeLinx logs I see 

4888: 2020 (Jun 08 2021/11:18:02.4850)[WARN]  Nomad: invalid CORS origin 'https://host.domain.name'

4888: 2020 (Jun 08 2021/11:18:02.4850)[HTTPAS]httpServerResponse: HTML pkt size: 560

HTTP/1.1 403 Permission Denied


The good news is HCL is on to it, and will hopefully have a update that fixes the problem soon. 

I will update this post when that happens.

Hopefully this information save you some time if you hit the same problem.

Solutions to the issue of using .ind files to compact

A recent blog contained an article discussing a bug in Compact where it does not correctly process file names or directories that have spaces in them.

Two immediate solutions come to mind:.

1 - If it is something you do infrequently or want to do it on a manual basis, just use DBMT. It will process .ind files correctly.

2 - If you want an automatic solution, that updates ODS levels,  DAOS enables database based on template name, and can do any number of other admin tasks, take a look at Defrag.NSF+ Just set and forget.
