I’m not familiar with the other products so can’t comment. Having said that, back in 2012 I led a project using ARCTOOLS in which we archived 394,465,391 million records in 238 hours.
I think some of the things you should compare between vendors are;
What modules/tables do they archive by default (for example, Payroll) – I believe this was relatively new for ARCTOOLS in 2012 and worked perfectly.
Check what some of your largest tables are and ask if these tables are archived ‘out of the box’
What’s the development process like should you want/need to create a custom archive on a table(s) not provided by the vendor?
When ready to archive Production data, can you archive during business hours or do you require an outage?
The ARCTOOLS installation is simple enough, maybe one hour tops
I can say there technical support is excellent, quick to respond during our entire project and very knowledgeable
Think about checking some customer references between vendors
Happy archiving.
