LTA Petablock Light

Data protection

The disks in the enclosures are checked for reliability during each transfer cycle. When a disk produces errors we move the data we can still read on that disk to another disk and mark the broken disk for replacement. When we disk is completly broken we mark this disk for replacement. When the disk is replace we build back the data from the other disk like in Raid. We know exactly the data that is stored on the disk and can prioritize which archive sets we first want to restore, this depents on the parity level.

Migrations

When you for example want to migrate disks from 2TB Seagete to 4TB Hitachi you simply mark the first 10 disks for migration. The next cycle the petablock is online we write all data to other disks and give the user an alert to replace the disks. When the new 4TB disks are online we write back the data and you can migrate the next 10 disks. This make the data migration automaticly, save and fast for replacing or expanding of your offline storage.

Data searchable

When archiving your data all the properties from every file and folder is indexed and saved into a database. This database is kept online and makes it possible to search though your offline data. When finding a file or folder you can simply see which archive set this belngs to and do a request to get the data back online on the next cycle.

Data gathering

The software is able to collect data manually or automatically with an advanced scheduling manager. The gathering can be from a local or network(CIFS) data source, including from a remote (WAN) source. Gathering of data can be incremental, for example when you want to archive the output of a document management system. The data can be collected on a daily, weekly, monthly or quarterly base.
