Restore operating system disk
Restoring the system volume as in the example above is an operation irreversible The operating system disk will be replaced by the snapshot and the server will be in the exact state of the backup date.
Data stored on data volume (vdb) is not affected by this operation.
Restore data disk (vdb)
Two modes of data restoration are possible:
1. Mode Read Only
If the size of the snapshot differs from the size of the volume, only this read-only mode is available.
This option allows to mount the image of the data snapshot, which allows read-only access to the data of the backup.
For information, here are some useful commands to exploit your backup:
- To access the main data volume:
mount /dev/vdb /mnt/. - To mount the data volume in a specific "backup" folder:
mount -o nouuid -o ro,norecovery /dev/vdc /backup.
For which letter to use (/dev/vd?), use the command lsblk:
2. Mode --Restore
The restoration of data volume is an operation irreversible The data disk (vdb) will be replaced by the snapshot. At the end of the restoration, it will be necessary to trace the volume of the data so that your operating system refreshes the content.
The following procedure and orders are provided for information purposes only:
- Make sure your data volume is not mounted:
* umount /mnt(/mnt or location you chose to access your data). - Upload the data volume:
* mount /dev/(vdb) /mnt
To know the name of the data volume attached to your server, use the command lsblk (see above).
