You could store a copy of your website in another location and reupload it during the next test. As explained in the announcement of the alpha release, at some point the Alpha 1 network will be stopped and all data will be lost. We’ll announce this in advance.
Data on this alpha network may get lost and MaidSafe will decide or require to wipe the data and restart the network with each alpha release. We will communicate these events via the SAFE Network Forum and on MaidSafe’s blog.
