The QoreStor seed operations allow for exporting data on the source to a portable seed device to then import the seed data to a primary target, and, if required, a secondary target as well. Replication seeding is an alternative to using network bandwidth for the initial re-synchronization of the source and target(s). After the target(s) are seeded, continuous replication can be started, which will keep the target(s) up to date by sending only unique data.
The QoreStor CLI seed commands support the following operations:
- Create a job to perform seeding export or import.
- Delete an existing seeding export or import job.
- Specify containers for seeding export.
- Remove a container which is already added for seeding export.
- Add a device to be used for seeding.
- Remove a device which is already added for seeding.
- Start seeding process (export/import).
- Stop running seeding process (export/import).
- Start cleaner to process seed ZL logs on target.

NOTE: The seeding device must be a CIFS share: a USB device connected to a Windows or Linux system and shared for import as a CIFS-mounted folder. |
|
|
NOTE: The following scenarios are not supported for seeding:
- Import AND export from one share/device cannot occur at the same time.
- Import from one share/device cannot be completed from multiple locations at the same time.
- Export to a mount point can be completed only from one seed job. Multiple seed export jobs cannot send data to a single mount point.

This topic introduces the
seed command usage:
- seed --create --op <options> [--enc_type <options>] [--storage_group_name <name>]
- seed --delete
- seed --add_container --name <container name>
- seed --remove_container --name <container name>
- seed --add_device --server <server name> --volume <volume> --username <user name> --domain <domain name>
- seed --remove_device
- seed --start
- seed --stop
- seed --show
- seed --cleanup
- seed --help
Description
Creates a seed export job of type import or export on the source QoreStor or DR. The command will prompt for a password, and this password will be requested on the target to import the data. The command allows you to specify the type of encryption that will be used to encrypt the data on the seed device. The default value is aes256. The default value for storage group name is DefaultGroup.
Syntax
seed --create --op <import|export> [--enc_type <aes128 | aes256>] [--storage_group_name <name>]
Where
--op Seeding operation export/import.
--enc_type Encryption type. Default value is aes256.
--storage_group_name Storage group name. Default value is DefaultGroup
Result
Enter password for seed export:
Re-enter password for seed export:
Successfully created seed job details.
Description
Adds the container(s) that you want to seed. A new invocation of seed --add_container command needs to be run for every container that you want to seed.
Syntax
seed --add_container --name <container name>
Where
--name Seeding export container
Result
Successfully added seed container.
