Restoring Backup Storage Location

[apavone]

Problem: Failed backup storage device.

The storage device used for client backup storage has failed and cannot be repaired.

There is no replication server.

I have a tape backup of the backup storage from several days ago.

Question: Is is possible to restore backup storage location and recover from this scenario without clients having to delete their backups and start backups "from scratch"?

If so, is there a procedure documented or a support article that I can reference?

If not, how should clients procede once the backup storage location is available again?

Tnaks.

Hi apavone,

StoreGrid backup server database consists basically of two set of data. One is the details of the customers, clients etc and the other is the meta data of the backup data. You need both these restored before the clients can resume backing up from where they left off.

For the second set of data, StoreGrid backup server has an inbuilt process that can be run to reconstruct the meta data from the backup data.

For the first set of data, in v3.x, StoreGrid's MySQL backup end database dumps the data as [dbname].sql file in the storage location on daily basis. If this file is still available intact, it can be used to construct the customer/client details. In v2.x installations, this data will be available in the sgserver.db file (or its .bak file) in the data/ folder . In case this file is not present, then please contact our support team. They will give you a recently enhanced executable which can construct the customer/client details from the backup data (1/ folder) itself.

In your case, we are not sure how much of the backup data is available on tape and the version of backup server you were running. Therefore, please contact our support team and they will work with you to see how the server can be brought back up from the backup data alone.

I will update this thread in a few days with a link to a well documented help file with the detail of the process to reconstruct the backup server from the backup data alone.
