Historical archiving creates
tamper and error resistance
When you use EasyCo mirrored systems, your data
is intrinsically preserved in two places. For an added layer of protection,
your file system will be electronically archived nightly in both places. We
will keep, and make available to you, the read-only copies of the last two nights,
and last two end-of-weeks. As these time-stamped copies are part of your file-system,
a few mouse-clicks at our administration application makes them instantly available
to you.
You might think that our archiving process consumes
a great deal of extra space. In fact, rsync and FTP only create a separate physical
copy of a document if that document actually does change. Otherwise, all they
do is create a link to the document in the historical archive list. Changed
linkages only occur when a changed version occurs. Thus separate physical copies
only occur when change happens. Thus, for instance, if someone were to get your
passwords and deface your site, the mere process of their loading new content
physically separates old content from new. Our 10 copies probably are overkill,
but they protect you if you don't get around to spotting errors or problems
for weeks or months.
For any given day, the archiving process will consume
only the space consumed by changed files plus a small amount to reference the
file name and size of all files. Per archive cycle, typically less than 3% of
the original space is required to preserve the archive version because most
web site file systems change infrequently.
