Looking for Windows Server backup software

You mean VM backup software, right?  I like Altaro myself.

Backups should be offline and disconnected (after completion of a backup cycle) and offsite weekly on a rotating basis.

High Capacity Tape Drive and Tapes work well.

We are exploring Azure backups but we need to ensure the offline part. Cost is comparable to tape; that is not vastly cheaper.

Backup for physical servers that works is not cheap.

Windows comes with it's own Backup Utility and can be targeted on any storage.

What are you looking to backup? (AD, Exchange, SQL, File Server.)
What's your planned target (tape, Disk 2 Disk, Cloud).
What's your total data?
What's your target window to complete?

From there you see if Windows and your resources can handle your requirements.

For files you can also leverage DFS replication to an off-site destination server.

Or Robocopy.

From there you will have to start looking at third party software like Backup Exec or others.

You've not included enough detail.

Wbadmin

What resources do you have, what are your requirements?.
Restore data, or restore entire server bare metal?

All we need to backup are folders containing files and the data from the Business Software.   I am researching for a customer of mine.  My company uses Arcserve but it is expensive.

They were using Genie Pro.  I contacted them and they will not let it be installed on a new server.

Acronis is great, but for Servers, it is $900.

Have you looked at local Cloud Options (not Azure)?  We have a small not-for-profit client doing that.

VM or not VM?  And what is "reasonable" in your opinion?

VM and under $300.  Have not looked into Cloud

The economics are excessively tough. I think the client here is around $800 annually (all in as there is no client labour and you do need to take time resources into account).

Acronis is great, but for Servers, it is $900.

Fair point. I guess "reasonably priced" is a fairly subjective term :)

All we need to backup are folders containing files and the data from the Business Software.   I am researching for a customer of mine.

Considered just using something like a DropBox buisness plan? If disk images aren't going to be involved, and only data files need to be secured, then that might be all that's needed to do the job for them?

What about veeam? How many hosts, VMs are involved.

If the data is important it's utterly foolish to skimp on the backup software.  My perspective.  Backup is Insurance.  You hate to have it.  You ate to pay for it.  But when you get into an accident or you get really sick or your house is destroyed in a hurricane or tornado, you're REALLY glad you have it.  When your hard drives crash or you get infected with ransomware, having backup is the difference between going out of business and recovering to continue business.  If the business isn't worth $600-700 for quality backup software, why are they in business?

There are low-cost solutions for data-only backups like this.  One such option is the free RoboCopy solution, included within Windows now.  Another is the shareware product called Beyond Compare, which is like RoboCopy in that it is extremely fast, but it ALSO has a GUI that can allow for manual synchronization or copying of data.  Both can be implemented via batch files and Task Scheduler to run overnight.  BC also has an option to sync with an FTP or SFTP site, for offsite backups.

You'd want to start by identifying the data to be backed up, the total size of the data, the rate of change, possible backup storage locations, available budget, need for off-line and off-site storage, need for OS backups, and other key metrics like this.  Some of these you have identified already, which helps.  Others may need some fleshing out yet.  For example, if they have 5 workstations, each with plenty of disk storage, you could run a BC sync from the server to one workstation on Monday, WS2 on Tuesday, WS3 on Wed, and so on.  This would give you 5 days of rolling backups, which increases your flexibility in restoring old files.  If there isn't storage space currently available, then your budget will definitely be a hindrance here, but I'd recommend installing a small NAS and using that for backup storage.

However, with the above solution, all copies are still on-line, and a malware attack could render them all useless!  So, you might want to consider a couple of external USB HDD's, and rotate copies to the offline storage as well, which also affords you off-site storage by taking them home.  Further, using BC to replicate to an FTP site somewhere (in the cloud, or at a principal's home) could also be extremely helpful in an emergency.  

Note that this ONLY covers data -- it doesn't cover the restoration of the OS.  If the OS/VM gets mangled, you're still down for hours or perhaps days while it gets fixed.  Making backup images with Veeam or some other similar VM backup solution may be sufficient for this.  (Personally, I use Acronis for my VM backups, and I *have* had to restore before!)

Thanks.  That a lot of good advice

The owner decided to go with Acronis.  Thanks to all for helping.
