Recovering the Citrix XenServer Host 63
Recovering the Citrix XenServer
Host
Whenever possible, leave the installed state of Citrix
®
XenServer
®
Dell™
Edition servers unaltered. That is, treat XenServer hosts as if they are
appliances and do not install any additional packages or start additional
services on them.
XenServer uses a per-host database to store metadata about virtual
machines (VMs) and associated resources such as storage and networking.
When combined with storage repositories (SRs), this database forms the
complete view of all VMs available across the pool. To make your XenServer
deployment readily recoverable, ensure to back up this database regularly.
Database Backup From XenServer Local Console
For the standard single XenServer case, you can back up the database using
the XenServer local console.
To back up the XenServer database with the XenServer local console:
1
Insert a removable media device (USB stick) to save the backup.
2 Select Backup, Restore and Update from the XenServer local console
menu and press <Enter>.
3 Select Backup Server State and press <Enter>.
You are prompted to select the removable media device you want to write
the backup to. Select the appropriate device and press <Enter>.
