Consistent with our servers getting backed up and very reliable.

It is a solid offering at a much better price than some rather well-known alternatives. Service is superb.

As we only have a relatively small setup I used the free edition available through Spiceworks (now withdrawn). I had a problem initially getting it configured to use a NAS as the backup destination but despite it being a free edition their support resolved the issue and I was then able to use it reasonably reliably for several years. Occasionally it would simply stop backing up for no apparent reason but never emailed to say the backup failed; it just stopped working altogether so sometimes it took several days before we realised the daily backup emails had stopped and we could then go in and reset the Unitrends VM which brought it back to life. The upgrades were generally easy to do, just click an upgrade link and wait until it finished, however the last time I did this it completely corrupted the VM making it unbootable. We then installed the latest version from scratch but again hit the prblem of it not backing up to the NAS. Unfortunately this time their support were very unhelpful refusing to give any support or advice unless I paid for a ridiculously expensive annual support contract. That caused us to look at competing products and we settled on Nakivo which is MUCH faster to do the full and incremental backups as well as having vastly superior compression so we can keep more backup history. I've not found anything that I used on Unitrends that's not easier and quicker to do with Nakivo and I paid less than the annual support cost for Unitrends! No brainer :-)

One of the great ways to keep data safe in a place or a cloud location with no limitation.

We love the product because it give us less time to restore in case of the emergency and also the learning curve is quick. The reports are also very informative so we can know exactly what is happening with the backups and make sure we can restore in case we needed.
