The data restoration feature is the most valuable because the end user requires minimum support to recover lost data.
Using the mobile client app has decreased the usage of portable storage devices for data transfer.
If I access my documents from the mobile app, I am also able to share these documents with accounts in other apps such as email, WhatsApp, Dropbox, google drive, etc. What I'd like is to be able to share a document or folder with other Mozy accounts (users), with limits of either under the same admin domains or even with other domains.
I have been using EMC Mozy Pro for three years.
We have not had stability issues.
We have not had scalability issues.
I have not been required to use support so far.
I have used a couple of other applications that use tapes and tape drives. These require daily or weekly physical change of tapes, which takes time. There is s large room for errors, such as inserting a wrong or faulty device, forgetting, etc.
It is easy to set up for manual client configurations. Automated client deployment was not straightforward and never worked for me.
The pricing is fair for the PCs, but very expensive for the servers.
We evaluated Druva. This is more expensive.
If you can afford it, then you must take it.
