♨ USENET Binary Retention ♨☛ A major differentiating factor between USENET providers is the degree of article retention ☚
▶ What is Usenet 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 4,400 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. The top recommended providers also store every header for the full retention length they advertise. Headers are not only needed to browse newsgroups for finding posts, but every newsreader with search uses headers to actually run their searches. Without them, you'll need to sign up with one of more NZB indexer... most of which require a subscription fee or are closed to new user registrations.
➜ Premium USENET providers have the highest retention rate of all the Newsgroup servers !!!!!. The top recommended providers store every article in every newsgroup on their server farms for the full retention period that they list on their website.
➜ Premium USENET providers continue to add storage capacity for more retention. It is also recommended that you choose a provider that consistently adds more storage and grows retention. This means the number of articles you have access to grows each day for the most complete Usenet experience possible.
➜ Premium USENET providers never expire the oldest files at unpredictable times. They keep data during all their retention.
➜ Premium USENET providers list an exact number of retention days on their website. You should not see confusing marketing copy like 'up to xxxx days retention,' 'with many articles available over x days.' Wherever you do see this, you can expect that the provider has not only poor retention rates, but also does not keep many or most of the articles for the full number of days they list (if they even give a retention # at at all). This is because they systematically delete articles, both old and new, from their servers. This is done to free up storage space, which will cause high incompletions compared to Usenet providers that have complete article retention.
➩ Mixed-mode binary retention.
➜ Some USENET providers claim more binary than they actually provide or give rough estimates of their retention times on their Home pages.
➜ USENET Providers are also starting to 'cache' retention. They provide a dual retention: they 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 - alt.binaries.mom) 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.
