Concat’s dsmISI products can dramatically boost backup performance when targeting NAS, as well as offering a great alternative to NDMP.
Backing up large network attached storage (NAS) data is typically a painful, clunky and unrealiable process.
Many backup using the Network Data Management Protocol (NDMP), a protocol that enables to transportation between NAS devices and backup devices.
The main advantage of NDMP is that it removes the need for transporting that data through the backup server itself and can directly offload to secondary storage.
However it does have quite a few pitfalls including the following:
The business realities of these pitfalls are:
So how do you provide a sustainable method to your company to backup NAS data and make each of those business realities of NDMP history?
The answer is simple via dsmISI MAGS
dsmISI MAGS in conjunction with IBM Spectrum Protect enables the incremental backup of large production file services for a wide range of NAS vendors including EMC, HDS, HP, IBM NetApp and for Windows file servers.
Spectrum Protect (previously TSM or ADSM or WDSF for the experienced veterans amongst us) is still the only software capable of continuously backing up file systems entirely incrementally. With extremely large file systems, containing many millions or even billions of objects, this approach, however, does have its limits. Very often the time used for identifying changed, new or deleted objects alone takes days or even weeks – and thus renders a service level which requires a daily backup cycle which is impossible to achieve.
General Storage dsmISI MAGS solves this fundamental problem by accelerating identification of changes and the resulting movement of data by orders of magnitude. Even extremely large and busy file systems can be backed up incrementally within a reasonable timespan using regular Spectrum Protect incremental backup when controlled by dsmISI MAGS.So how does it work?
MAGS is in effect a wrapper for the Windows Spectrum Protect client, designed to accelerate backups of NTFS, CIFS & SMB file systems with many objects. MAGS does not interfere with what Spectrum Protect does or does not do. It merely starts many Spectrum Protect clients in parallel to assure faster backups and restores. The general concept of how MAGS works is pictured below, yes it really is quite simple!
MAGS runs on a Windows server and has the following requirements:
From version 1.1 MAGS monitoring and configuration are based on a web interface. From MAGS CONFIG you can alter the web port the webserver is configured under (8088 by default), ensure a valid license key is active, install the service, uninstall the service, start, stop and restart the MAGS web server service.
Once the web service is installed and running your flying and can access the MAGS web interface so assist setting up backups, monitoring backups and setting up parallel restores to run.
Scheduled backups run via Spectrum Protect have to call on a .cmd containing a command to run the mags executable and referencing the MAGS option file created via the web interface during setup. You will have obviously needed to configure the schedule in Spectrum Protect to run the .cmd which should be located on the MAGS proxy server, associated the MAGS proxy node with the schedule, setup the client scheduler on the MAGS proxy node and ensured the scheduler is running via an ID that can access the fileshare to be backed up via MAGS.
First full backups will typically take a considerable period of time, this depends on a number of factors including the size of the fileshare, number of files and underlying infrastructure for the MAGS proxy and Spectrum Protect server. However once the first full is complete incremental forever backups are possible and the real business benefits of MAGS are realised.
So what are the real business benefits of MAGS?
Sounds great, how do I see it in action?
We can quickly setup a proof of concept and use a 30 day trial license for dsmISI MAGS to enable the solution to be proven before you replace NDMP or your existing backup solution for your filesystems with it.
