Windows 2012 Backup


On a new DELL PE R320 server I am planning to backup 1Tb of data every night on external mini-USB3 2Tb drives

Only files to backups no special application

I will use Windows 2012 backup to backup the whole server

All USB ports on the DELL PE R320 are USB2. THere are no USB3 ports

I Wonder if I will be able to backup 1To of data every night (about 8 hours) in USB2. Is it not too much?

By default Windows 2008/2012 backup will schedure "complete" backups
Maybe an option will be to Schedule incremental backups instead of complete backups. Is it OK and safe?

Another option may be to add a PCIe USB3 card in the server ? should it be faster ?

Thank you for your help and advise

Yes, USB3 is much more better than USB2 in term of speed, power consumption, etc, but I would question why will you want to be backing up the same 1TB data every day? It is better to set up a backup schedule as follow after the initial full backup.

Monday to Thursday             Incremental
Friday                       Full
Montly                      Full

With the rotation as follow
Weekly reuse
Monthly archive

Or better still use robocopy to synchronise the source and destination folder (your USBdrive)

All you just need to schedule this to run as schedule task and from then it will just be copy the changes.

Note that this robcopy is not a back up solution so it will not back up your system data state.

Let me know if you need the script for robocopy.

I need to use Windows 2008/2012 Backup since it is an incremental backup so I will be able to restore data from different backup dates (from last week, last month, ect...)

Your ROBOCOPY solution seems good but it just keeps ONE backup, the last one,  (and erase old backup) is it? Can you confirm this point? can I restore a file from las week backup? (with Windows 2010 backup it is indeed possible)

Thank you very much

As I said earlier, the Robocopy solution is not a back op solution, it just copy and keep a mirror copy of the source directory, you cannot go back o the old one as it just replicate the source.

It's worth noting that you cannot mix backup schedules with Windows Server Backup. So, you can't schedule Full backups for Friday, then Incremental the rest of the week.

You can get around this by using the cmd line tool wbadmin and scheduled tasks, but it's not as straightforward as a few clicks in the GUI.

Whilst this blog is for 2008, you can still use wbadmin on 2012.  There may also be powershell cmdlets in 2012 but I'm not on a box to check.

As for your questions, agree, USB3 will be much better if USB storage is your option. However, if you are using incremental backups WSB uses block level methods for backing up (instead of file level) so it should be OK as it just backs up the block changes to file(s) instead of the whole file(s).

As with any solution, a backup is only good if you can recover from it, create a VM in an isolated network and try restoring to it. If it helps, document the process so when a disaster does happen, you don't have to worry about finding the commands to restore, etc.
