pctl suspend and pctl resume

The pctl suspend command is used to save the state of a running Container. It has the following syntax:

pctl suspend < CT_ID >

During the pctl suspend execution, the current Container state is saved to a special dump file and the Container itself is stopped. The created dump file is saved to the Dump file in the /vz/private/ CT_ID /dump directory on the server (or in the directory specified as the value of the DUMPDIR parameter in the Parallels Server Bare Metal global file).

The pctl resume command is used to restore the Container from its dump file created with the pctl suspend command. It has the following syntax:

pctl resume < CT_ID >

When executed, pctl resume searches for the Dump file in the /vz/private/ CT_ID /dump directory on the server and restores the Container from this file.You can restore the Container dump file on the Source Server, i.e. on the server where this Container was running before its dumping, or transfer the dump file to another server and restore it there.

Note: Before restoring a Container from its dump file, make sure that the file system on the Destination Server is identical to that at the moment of the Container dumping. Otherwise, the Container restoration may fail.
