NASdeluxe Recovery

Possible break down causes for NASdeluxe iSCSI/NAS devices

The most recurrent break down cause statistically for a NASdeluxe Network Attached Storage from Starline Computer is the physical defect of the data media. Dependent on the configuration used (RAID 0, JBOD, RAID 1, RAID 5, RAID6, RAID 50 or RAID 60), access to the iSCSI/NAS volumes is no longer possible after one or more data media break down. Consequently Hyper V virtualizations and the data inside them are also nit accessible any more. If a 256Bit AES encryption of the RAID volume or thin provisioning was used additionally, inexperienced rescue attempts may aggravate the error pattern or completely impede a successful data rescue. Severe damage may also occur on the logical file system level (Windows Server 2012 R2 or EXT3, EXT4 or XFS with multiple file systems).

Starline Computer Ltd. NASdeluxe Network Attached Storage devices are often used for administrating or saving large datasets. But NAS systems are also prone to data loss. Particularly with high end enterprise solutions it often happens that network structures like VDI systems or more complex virtualizations suddenly are not accessible any more.

Even if you may feel safe with Data Guard backup solution or other backup solutions, we regularly receive inquiries from clients with old, inconsistent, corruptive or lost automatic snapshots, so the predefined internal recovery process is not executable and only a data rescue can help. Especially with mechanical defects you should not try to fix anything on your own, but contact a professional data rescue company.

How to prevent consequential damage with NASdeluxe iSCSI/NAS systems

• Keep calm! Panicky rescue attempts may cause severe consequential damage.

• Give us a call! Avoid reboots, rebuilds, chkdsks or similar operations. They may complicate the data rescue.

• Don't move snapshots or copies back to the live system and avoid installations, storing processes or accesses to prevent further data loss.

• Don't perform any further installations and don't save any new data.

• Shut down the affected system. The longer it continues to run, the more fatal the damage gets.
