backups, backups - the bane of our existence. But if you're
a network or IT manager, backups are a way of life. The big
problem is quickly getting at individual files within backed
up data, whenever they're needed, avoiding costly delays and
downtime in the process. So if you can imagine a situation
in which certain directories on client computers scattered
around a typical network are backed up transparently and automatically,
after which the data can be accessed by a client computer
through a web browser, then you understand the basic premise
behind Replicator. Couple that basic application with the
ability to automatically move infrequently used data to lower
cost storage media (moving it back to active network storage
drives only when needed), while keeping high-usage data ready
at hand in network area storage or active servers, and you've
got a good overview of the serious replication, archival,
data storage and data retrieval power in Replicator.
can be installed on most Linux and Solaris-based servers,
replicating data from selected clients throughout a network
(LAN, WAN or Internet), then storing the data in local and/or
off-site media. Replicator is designed to maintain the latest
copy of your data, create archive copies of the data and generate
a data history. Replicator allows clients to retrieve their
latest replicated data or any one of their archived copies
without outside assistance. It will replicate data from virtually
any client computer running any standard client operating
system. Replicator manages complete file systems, specific
directories and/or files. We performed our usage tests with
three different SunSparc servers, all running SunOS 5.7.
to do with tape backup and data encryption systems is easy.
Media failures, drive failures and other problems abound.
Hard drives are cheap and easy these days however, so can
we please kill tapes? Please? By the same token, nothing to
do with any Linux or Solaris installation is ever easy either.
The scope of this review is too limited to go into all the
details. It's sufficient to say that everStor's technical
support seems to be up to the task of getting problem areas
sorted out. If you have any flaky network segments or nodes,
we recommend fixing them before horsing around with Replicator.
After installation, a Network Administrator can get into the
GUI via IE or Netscape to select the replication frequency
for each data set, create configurations, etc.
configured Replicator for part of our WAN (in three separate
server locations in the Toronto, Canada area) using Replicator's
server-to-server function. We set up a higher level Replicator
corporate server to replicate data from lower level Replicator
servers. The lower level Replicator servers grabbed data from
local workstations and servers. For security purposes and
according to the very insistent advice from everStor tech
support and the product documentation, each client's data
was stored in a directory tree on a destination disk unique
to the client. It was a bit of a pain to set up, but it worked
well. We gave a couple of client computer users their own
server to control along with a password which allowed them
to set up custom directories, replication frequency and selective
restore. This also worked well (except for one individual,
who shall remain nameless, who insisted on trying to delete
existing directories while creating his own. BAD DOG!). Geez.
Since the Replicator GUI is web-based it requires an operating
web server - OK for many applications but relatively insecure
for WAN-based applications (you've got to open a server port
and all that). There are several firewall and security issues
here. Replicator is designed to replicate only data changed
since the last replication action and we're trying to figure
out why everStor didn't add full backup capabilities to the
product (thereby providing IT managers with a seriously heavy-duty,
comprehensive data tool).
Good quality middle-ware that fits nicely between full backup
policies and the need for automated, high-speed, incremental
data backup & retrieval for clients and servers throughout
a network. You can select the replication frequency of a data
set while preserving the network bandwidth needed to conduct
your normal business activities. Replicator is excellent for
replicating critical configuration files, customer data and
for data recovery needs caused by buggy productivity software.
Mission critical password, revenue and inventory files can
be replicated at higher frequency rates than less critical
files. everStor also makes something called the jb Driver
(a reasonably intelligent robotics driver for controlling
tape libraries and optical jukeboxes) which in conjunction
with Replicator, may make the job of managing storage media
drive stacks significantly easier. Apparently decent sales
support engineering staff. Good stuff.
