which backup company is best/inexpensive for disk to disk solutions

I am currently backing up about 7TB of data, file, SQL and Exchange, with the bulk of the storage coming from files.
I am backing up about 5 different Windows servers.  We are currently using veritas backup exec and are backing up to 2 superloader 3 devices, one with LTO7 and one with LTO6.
The backup jobs are taking longer than the entire night and I'm thinking it time to upgrade to backup directly to disk.
So I'm thinking to go to disk to disk to disk, and I would like the disks to be hot swap-able, so I can remove them every day and store them in our fireproof safe until I have to reuse it, which would be once a month, as I'll have like 20 disks, one for each day the backup runs.

Any idea's what's the best way to proceed?  I've been doing some research and there's so many companies out there, that I wanted to know if anyone has had good success with any particular solution?
I would want something that supports at least 8TB drives, so I can do a full backup every night to a single drive.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you're running backups to a remote site, then your net connection speed will come into play.

Most backup systems are stupid + (to me) do backups all wrong.

Easy solution, have someone in your company with a high speed connection (Google 1G Fiber is what I run) + setup a Dobro box.

Even a small unit with 5 slots will give you 5 * 12Tb == 60Tb total with 1 spare, so 48Tb total space.

This will cost a one time outlay of $2500, so no monthly charge.

Then just aim your backup at this device.

I'd personally get rsync running (Cygwin or other approach), so your backups are smart (only transfer parts of changed files).

So the way I run backups is...

1) rsync remote data to a backup machine, so this step runs very fast because even for multi-Terabyte SQL databases, only a small amount of data changes.

2) shutdown databases + do 2nd rsync, to flush memory buffers to disk, so clone of data is congruent/consistent.

3) restart databases

4) on backup machine generate either full backup files or incremental backup files, against cloned data.

This step is important + where most backups fail completely. Most backup systems attempt to generate a local backup first + then transfer the entire backup file, so you end up in the situation you described...

Where one backup can't finish before the next one starts.

The approach I describe above, allows me to backup 100s of large sites in a matter of a few minutes each night.

Well, steps #1-#3 usually takes <1 minute/site + step #4 just churns away till it's done, usually many hours when generating full backups.

This churn has no effect on production sites though, as the backup machine... is just a backup machine...

Thanks for the info.  So I'm already covered with offsite backups, I do have a vendor that backs up our servers off site.

I'm looking for a local solution. I want to backup the same servers to tape so I can have it in a fireproof safe just in-case.
I was contemplating to moving to backup to disk to store that in a fireproof safe, but perhaps that might not be the best option?
RDX removable disk store device by tandberg...  Basically a SATA HDD inside a removable cartridge.  I completely eliminated tape backups (its cheaper and i can store more data).  The cartridges should still be able to fit into your fire safe for storage.

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

RDX 8000...  With dedup you will most likely be surprised how much less physical disk space you need for 8tb of backup data.

Thanks, but highest capacity they offer is 4TB.  I need at least 8TB.

High-Rely makes some network and USB based destination storage. The NAS series receives the backups and replicates them to another RAIDPac that you then rotate.

Veeam and StorageCraft are about the best backup products out there. Veeam backs up via the host while StorageCraft backs up in-guest. Both offer continuous incremental backups so that a FULL does not have to run on a weekly, bi-weekly, or monthly schedule. Both manage the backup chains efficiently and can set up grandfathering on the chains to produce FULL sets for archival purposes.

Backup is an investment not an expense. We get what we pay for. We'd _never_ trust our backups to BackupExec. BTDT

If you use a staging area to create an entire copy of all your files to backup... then massively compress these files, like pixz -8, then you may require far smaller tapes to make your backups.

In fact, if you're backing up a massive amount of duplicate data every night, then you might just use something like...

tar -Ipixz -cvf $ts-archive.txz -C /path-to-directory-top file(s) dirs(s)

Open in new window

Or something similar, then backup $ts-archive.txz to your tape system.

David, I'm using windows and I think the tar command is for linux.
Plus, I get what you are saying, but the drawback to creating multiple steps is everytime I need to restore something, and it's usually critical or in an urgent time frame, after I restore it, I will have to decompress it, so I can extract the data I need, which adds another layer.
David FavorLinux/LXD/WordPress/Hosting SavantCommented:
Windows (shudder)...

I'd Google the following - time machine windows equivalent - which turns up 1.5M results.

Pick a system which allows you to easily restore, then follow my first post for setting up a Dobro box with 12TB disks.

A very cheap way to go.
DanNetwork EngineerAuthor Commented:
David, the problem is, I"m not just backing up 1 server, but I'm backing up 5 different servers, a few of them are SQL, 1 exchange and 2 file servers, so it's a bit more complicated to back that up to a "time machine" equivalent to for windows. Yes, I can get a drobo or a synology with 10 or 12 TB disks, but I also want the data on either a tape or removable disk, as that is one of my director's requirements, to have the backups in a fire proof safe.

High-Rely? StorageCraft? Veeam?

The High-Rely RAIDFrame single RAIDPac setup would work for your scenario.
