Virtualization ecosystem is becoming multi-hypervisor

6 February 2012
Comments off

Reading Time: 3 minutes One trend in the last year(s) is that the virtualization ecosystem is growing outside the boundary where was born: historical partner vendor of VMware now are extending their solution to other hypervisors, and also also new products are designed to managed a more complex virtual environment. This was also called “Hypervisor Agnosticism” in a VKernel post. We do not talk about interoperability across different hypervisors, but simple use same tools, especially for management, monitoring and data protection, for more type of products. Does it make sense? For a single customer maybe not… have multiple environment […]

Is VTL dead?

25 January 2012
Comments off

Reading Time: 3 minutes One curios thing of both ExaGrid and Dell DR4000 solutions (but also other solutions) is that they lack of a Virtual Tape Library (VTL) feature and only work as a network share (with CIFS or NFS). In both cases the reason was not technical (but I think that the main reason is still just a way to reduce cost and complexity) but marketing/strategy (customers just don’t ask at this feature). But moving from a backup to tape (B2T) to a backup to disk (B2D) solution does not necessary mean move to backup to file (over […]

Is backup to tape dead?

24 January 2012
Comments off

Reading Time: 3 minutes Several new solutions seem demonstrate that backup destination is moving from tape to disk. It isn’t really a new trend of last year (for example see this paper from Lisa 2006, or Microsoft that has removed the tape support in his OS included backup solution starting from Windows Vista), but now more products are pointing to the disk solution. The Linear Tape Open (LTO) consortium (whose member include Hewlett-Packard, IBM, and Quantum) has officially released specifications for the LTO Generation 5 with around 1,5 TB of native capacity and a throughput of 140MBps (uncompressed)… and […]

Veeam Backup & Replication – Understand the backup format

4 January 2012
Comments off

Reading Time: 2 minutes Compared to other backup software, Veeam Backup & Replication has several formats to save and handle the backup files. As you can see in the Advanced Settings for each backup jobs there are different formats (or mode) where the files are saved: Reversed incremental: the last file is a full version and past files are re-calculated as delta files. Incremental: the first file is a full one and on each backup jobs is created a new delta file. Incremental with synthetic full: similar to the previous but a new full file is periodically re-calculated. Incremental with […]

Veeam Backup & Replication – SAN Transport Mode

3 January 2012
Comments off

Reading Time: 2 minutes The SAN Transport Mode is a way to implement a LAN-free backup solution when the backup server is a physical machine and have a direct access to the VMFS datastores. This method was first provided by the VCB Framework and then ported to the vStorage API related to backup and data protection. In order to use this method in the proper way, some configurations and considerations are required:

Why Dynamic Disks are a bad choice

22 December 2011
Comments off

Reading Time: 3 minutes Microsoft Windows Dynamic Disks (or Dynamic Volumes) are an abstraction layer (introduced in Windows 2000) over the partitions (similar to the LVM layer on Linux environment) to decoupled the volumes (with their NTFS data) from the disk partitions and have a greater flexibility, like hot-extend a volume by simple add new partitions (but also several other advantages). But in a virtual environment there are other way to handle disk flexibility, like hot-extend a virtual disk at hypervisor level (for VMware this feature was introduced in VI 3.5U2)… so there is no need to use dynamic […]
