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