Usenet Retention

A major differentiating factor between Usenet providers is the degree of article retention.

What is Usenet newsgroup binary retention?

Retention refers to the length of time that a post is available to subscribers. Binary Retention means the time the Usenet server keeps articles around before they expire. On each Usenet server the administrator will determine the retention for each Usenet newsgroup usually by allotting it a certain amount of hard drive space.

Currently top Usenet providers surpass 4,200 days of binary retention. In other words, you can access files that were uploaded to Usenet in 2009. But of course, not all Usenet services offer the same number of retention period days. Generally binary retention is much weaker with European servers than it is in the USA. Only Eweka (Europe-based service) can rival the retention of American Usenet providers.

Why is it important when choosing a Usenet provider?

Retention is an important consideration when it comes to choosing a Usenet provider. It provides information on how long a message or a file remains available in the newsgroups and/or is saved there. A long retention time therefore means that content can be found, read and downloaded for longer in the Usenet. High retention is a good thing and it's one of the points that makes Usenet the ideal place to search stuff.

Retention rules vary by Usenet providers

It’s important to check the type of retention the Usenet Provider advertises. Not all Usenet services don't have the same quality. There are two kinds of retention:

Full binary retention. Full Binary retention is probably the most important thing to take note of when looking for a Usenet service provider. Premium Usenet providers offer the highest quality retention:

Full local retention: Premium Usenet providers have retention on their own storage (only local retention). They are completely tier 1 backbone. No cache retention, only local article storage.

Full Header retention is a major feature, a very important factor. Premium providers have a header retention that matches their article retention (or Message ID). Users will be able to search all the available binary articles without the need for NZBs or an NZB search index. The reason for not fully support the use of headers comes with the fact that headers eats up a lot of bandwidth thats totally unnecessarily.

Premium Usenet providers have the highest retention rate of all the newsgroup servers !!!!!

Dual binary retention: Some providers claim more binary than they actually provide.

Some Usenet providers give rough estimates of their retention times on their Home pages.

Usenet Providers are also starting to 'cache' retention. Some Usenet providers have some local article storage and articles outside of their own retention are pulled from a third party backbone. They cooperate to share storage with another provider.

Lately some providers have begun advertising 'Popular retention': Meaning they say they have 1 year of retention, for example, but do not actually keep articles for that long if they are not 'requested' by enough users on their servers in a specific point in time. If they need space, they can delete older files to make room which result in a partial binary retention.

All Newsgroups do not have the same retention. The biggest Newsgroups (alt.binaries.boneless - have weaker retention because a greater number of fiels posted means lower storage capacity for the servers.

Some Usenet providers provide less Header retention than NZB retention. The reason for not fully support the use of headers comes with the fact that headers eats up a lot of bandwidth.

Our TIP: Don’t overlook the retention rate offered by Usenet providers. Aim for a provider with Full binary retention

Best Usenet Binary Retention

Newshsoting Binary retention

Newshosting has the best Usenet retention rates in the market with a binary retention rate of 4,200 days and still growing daily. Text retention is also currently at 4,050 days.

That means Newshosting subscribers can access binaries that were added to Usenet newsgroups up to 11 years ago.

Newshosting also delivers the highest quality newsgroup retention.

You'll always see the same unlimited speeds whether the article was posted 30 days or 4,200 days ago.

All Newsgroups have the same retention. Other providers may advertise 1 year of retention, but in reality only provide 1 year of retention for a handful of newsgroups or article sets, meaning the number of articles you can really access on their servers is only a fraction of what is being advertised. The difference in a full retention server like Newshosting and a partial retention server is billions of articles -- a massive difference when it comes to the number of files you can access.
