Binary / Text Retention
Retention is one of the most important criteria in choosing a Usenet newsgroup service. Retention is generally defined as how long a post or article stays active on the Usenet providers' server before it expires or is deleted. Usenet providers only have so much storage on their servers. Once the allocated disk space is used older articles are deleted to make room for the newer articles. For example, if a provider says they have 500 days of retention, it will take 500 days for an article to drop off their servers.
When evaluating a Usenet vendor's retention, make sure to test the retention in hierarchies or groups of interest. Some Newsgroup providers keep retention uniform across all groups. Most providers keep different retention levels depending on the type of group - Binary and Text. Some providers keep long retention rates in a handful of binary groups or just the more popular groups so they can advertise higher retention. Accurate or misleading advertising depending on your perspective. Bottom line...test before you buy. Free trials are great for testing retetntion.
