Planning Offsite Backup Jobs

[y1008946]

Hi, we are looking to buy a server to store copies of local backups offsite using Veeam, backup copy jobs and the WAN accelerator.

Before we take the plunge and buy a new server, we would like to try and estimate what is possible with our size of system and our WAN link.

We have 8 VMs which take up 1TB of storage.

Is there a way to calculate roughly what size a nightly reversal incremental backup would be?

We only have an upload speed of 1 mb/s and we are trying to find out if it will be enough to run a backup copy job in 24 hours.

Many thanks

Very much dependent on workload, the amount of changes can vary from 2% to 30% of VM size daily (with 3-5% being most typical for regular servers, and 20-30% for highly transactional servers like Exchange or SQL). Best way to find out is to start doing local backups, and take a look at the job reports.

Also remember that WAN acceleration will reduce off-site backup traffic at least 10-20 times. Based on the numbers from our own internal deployment, I am pretty confident you will be able to do the offsite backup of your VMs in less than 24 hours if you use WAN acceleration.
