Uploading files to just another hoster is however no guarantee that the files stay available for a longer time. It should be clear by now that you need to have backups available either locally or in another location to reduce the likelihood that you will lose the data completely.

Mirror Services

One option that you have is to use so called mirror services such as Mirror Creator to distribute the files to multiple online hosting services. If one or two go down, you still have them available on others that you have selected.

The process of uploading files to those hosters is almost identical, with the difference that you cannot make use of existing accounts and their benefits.

• Select files that you want to upload from your computer. A file limit is always displayed, in the case of MirrorCreator it is 500 Megabytes for free users.
• Select the file hosting services you want to distribute your files to. Free users can select up to ten services.
• Start to upload the files once, the mirror creation service will take care of the rest.

Here is a short list of file mirror creation services:

• Gazup! – Supports six services in total, maximum file size 400 Megabyte if only four are selected.
• Upload On All – Supports 12 services in total of which ten can be selected for distribution. Maximum file size is 300 Megabytes per upload.
• Digzip – Lets you pick eight mirrors from a list of 18. Maximum upload size is 200 Megabytes.
• Multi Upload – Upload to a total of nine different file hosting services
• Upload Mirrors – Select up to 14 mirror servers where you want your files to be hosted. No information about file size limitations posted on site.

You can search for file hosting mirrors and similar phrases to find more services that distribute files for you.

Nothing changes for free users who stay below the upload maximum. Users who need to upload larger files have a few options as well. They could split the files using software like 7-zip or Haozip for this. Other services may be offered, for instance the option to delete uploads again, that are not available when mirror uploading services are used.

If you want to use a specific service, for instance because of the account benefits it provides, you should consider backing up your data at a second cloud hosting service to avoid total data loss if that particular services is no longer available. A suggestion here would be to use a backup and synchronization provider like Dropbox, or if more storage space is required Skydrive from Microsoft. This means however that you will have to upload the files at least twice for this. You could alternatively back them on a local device if you do not want to waste the bandwidth.

Have another suggestion? Lets discuss it in the comments.

Mirror Fox is a rather new service that will distribute files that are uploaded to the website to 14 different file hosting services. The services has an upload limit of 500 Megabytes per file and can be used anonymously. Upload speed to the service and distribution speed was excellent during tests. Files with a size of about ten Megabytes were distributed almost instantly to the other file hosting services and available for download almost immediately.

Mirror Fox will create one url on their server that lists the links pointing to the uploaded file on the other file hosting websites. A status is displayed that indicates if the upload to the specific file hosting service was successful or a failure. The status will also display if the upload is still in progress.

The initial links that are pointing to the file hosting servers are routed through a Linkbucks advertisement page. This should not be a huge problem for most users who have the opportunity to copy and paste the direct links to the files afterwards.

Speed and performance are usually better if a service is new and not swarmed by users. It can very well be that the performance of the file uploading and mirroring service degrades with a rise in popularity.

Mirror Fox supports remote uploads as well. The user has to provide an url that is pointing to a file that is between 1 and 100 Megabytes in size. The service will automatically distribute the file to the various file hosting websites. Mirror Fox via Genbeta
