Manual backup

Edit online

The backup process involves creating a copy of the data volume from the source system and securely storing it for future recovery.

Procedure

  1. List all running instances: 
    virsh list --all
    Sample output 
    Id   Name            State  
------------------------------ 
1   goveng    running
  2. List all block devices attached to the CCRT domain: 
    virsh domblklist <domain-name>
    Sample output 
    Target     Source 
------------------------------ 
vda          goveng_ccrt 
vdb          goveng_cloudinit 
vdc          goveng_db
  3. List storage pools: 
    virsh pool-list
    Name                      State          Autostart
------------------------------------------------
storagedirpool       active              yes
  4. List volume inside storage pool: 
    virsh vol-list <storage-pool-name>
    Name                                    Path 
---------------------------------------------------------------------- 
ccrt                             /var/lib/libvirt/images/storage/ccrt
goveng_cloudinit            /var/lib/libvirt/images/storage/goveng_cloudinit 
goveng_db                   /var/lib/libvirt/images/storage/goveng_db 
goveng_ccrt                /var/lib/libvirt/images/storage/goveng_ccrt
    In this example, hsm_signer_db is the data volume to back up.
  5. Compress the data volume: 
    zip -r <zip-file> <data-volume>
    Sample output 
    zip -r goveng_db.zip goveng_db
updating: goveng (deflated 1%)
  6. Copy the compressed file to the target LPAR.
