Server Migration

Post by pointblank » Wed Nov 02, 2016 4:58 pm

Hi Everyone,

I am migrating my file server from Windows Server 2003 to Windows Server 2012 R2 which requires a move of about 10 TBs of data.

What is the optimum profile setup to copy this much data over a weekend? I will need to keep the NTFS file and folder permissions.

Thanks.

Hi,

SyncBackPro can transfer files as fast as the infrastructure allow us to do. However, the copy speed depends on several factors like network speed, disk speed, CPU, the total number of files to scan on Source and Destination, their paths, the size of the total files that are going to be copied (a lot of small files would copy much slower than, several large sized files) etc., In addition, the profile run time might increase if you have enabled special settings in your Profile configuration like encryption, hashing, verification.

Assuming that your Source and Destination servers are on different locations (or network), transferring large amounts of data (~10 TB) over WAN would be very slow. Perhaps you can try hard disk seeding - where you can create a backup profile in SyncBackPro to run the initial backup from Windows 2003 server to an external drive. Then bring this external drive over to the destination server and transfer the data from the external drive to Windows Server 2012 (using SyncBackPro). This speeds up the migration process and copies NTFS security permissions, and Last Modified date stamps successfully from your source to destination server.

If both servers are in the same LAN environment, then you can simply use UNC paths (\\HostName\ShareName\ or \\IPAddress\ShareName\) to transfer files from Windows 2003 server to Windows 2012 server. Alternatively, you can install SyncBack Touch on your remote server and SyncBackPro on your local server and create a profile in SyncBackPro to connect to the remote Touch device to perform backup over the network. Please note that the latest version of SyncBack Touch supports multi-threading, so it can transfer files in multiple threads. Please read the Help file > SyncBack Touch > Transfer threads for more details. With SyncBack Touch settings page opened, press F1 to open the contextual help.

You can refer to the below links for more details about SyncBack Touch and how to create and configure a Touch profile:

Thanks for the detailed reply.

Both servers are on a LAN connected via a 1 Gb switch.

My questions is there any speed advantage using hard seeding vs UNC? the server 2003 is using USB 2.0 which has a max transfer of 480 Mbs and the server 2012 uses USB 3.0 with a max transfer of 5 Gbps. The backup will be slower than the restore and it is a 2 step process while using UNC is one step at 1 Gbps.

If i use UNC, does having SyncBack touch installed help with the speed since it supports multi-threading?

Hi,

SyncBack will transfer as fast as the given resources allow it to do and is limited by the protocols used (for example, USB2, etc). However, it's impossible for us to give a definitive answer on which method is faster on your end as the speed may depend on many factors (as explained above) and will vary from one environment to another.

Therefore, I would suggest creating test profiles using UNC paths, hard disk seeding and SyncBack Touch and transfer 5 GB of test data from Source to the destination server. Then compare their profile run times to find the approach that is suitable for your environment.

Thank you.
