Long time forum reader, but first post. Need a little help please!
Looking for the best way to backup 2TB of critical data offsite.

Around 50GB of new data added each week, not compressible so online backup is out of the picture.
Current plan is to move the data to a Synology 1512+ to allow for expansion without having to migrate to new drives each year.

Backups are only required once a day. Files are rarely changed but previous versions are needed in case of corruption/accidental deletion.
Ideally the solution would be to take the data container (disks/tapes) offsite at the end of the day and bring another set back in the next day for the following backup.

Thanks in advance and I hope there's someone out there with a brilliant solution I haven't thought of!
 
After your example, I googled related stuff and I think you've guided me in the right direction.

For a full backup I would need to be present to swap tapes, correct?

LTO4 is 800GB, so 3 tapes for my current data, and LTO5 is 1.5TB so two tapes. Any recommendation as to which drive/tapes to go for?

Thanks again.
 
Unfortunately the data won't compress so 1.5TB is probably about right.
Good to know LTO will be increasing though.

Just wondering if there is any way to solve this with disks, due to the £1200 tape drive cost. Is there any software/hardware out there which will perform a full backup split over multiple disks, then incrementally to a different disk each weekday etc?

I think I know how this might go, but got to ask a stupid question right?
 
Wow that's a detailed post, thanks.

Think that may be a little overkill for what I need though!

I would like to do differential/incremental.

In future though when the amount of data I have is greater than an affordable hard disk, the full backup will have to be split over multiple disks.

What I need is some software that will let me do a full backup once a week split over 2 disks, then incrementally to a separate disk each day. Just can't seem to find it.

Would Backup Exec be the kind of thing I'm after then? Sorry if I've not been clear.
 
Ok so rule disks out then.

I have zero experience with tapes.

At the moment all data is stored on a windows desktop.

What would I need to get a tape backup solution going in a Grandfather-Father-Son style of rotation? I.e. at the end of the week I have an incremental backup of each day, end of the month I have a backup of each week, and at the end of the year I have a backup from each month.

LTO-5 Tape drive
Backup software
Around 36 LTO-5 Tapes (currently have 2TB of data, so full backup will be 2 tapes)

Am I missing anything? This is only a small company so the cheapest reliable way possible is needed! Am willing to change tapes manually etc.

Just can't believe the headache once the data has outgrown two external HDDs rotating daily with incrementals on!

Thanks for your time on this, much appreciated.
