Overview

Deprecated.

Use the long-running operation returned by Admin::Database.database_admin.create_backup instead.

Job

A resource representing the long-running, asynchronous processing of backup creation. The job can be refreshed to retrieve the backup object once the operation has been completed.

See Database#create_backup

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

database = spanner.database "my-instance", "my-database"
expire_time = Time.now + 36000
job = database.create_backup "my-backup", expire_time

job.done? #=> false
job.reload! # API call
job.done? #=> true

if job.error?
  status = job.error
else
  backup = job.backup
end

#backup ⇒ Backup?

The backup is the object of the operation.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

database = spanner.database "my-instance", "my-database"
expire_time = Time.now + 36000
job = database.create_backup "my-backup", expire_time

job.done? #=> false
job.reload!
job.done? #=> true
backup = job.backup

Returns:

  • (Backup, nil) —

    The backup, or nil if the operation is not complete.

end

#error ⇒ Google::Cloud::Spanner::Status?

The status if the operation associated with this job produced an error.

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

database = spanner.database "my-instance", "my-database"

Examples:

require "google/cloud/spanner"

spanner = Google::Cloud::Spanner.new

database = spanner.database "my-instance", "my-database"
expire_time = Time.now + 36000
job = database.create_backup "my-backup", expire_time

spanner = Google::Cloud::Spanner.new

database = spanner.database "my-instance", "my-database"
expire_time = Time.now + 36000
