Alcatel-Lucent 7450 ESS-12 Configuration Manual page 445

If "config redundancy rollback-sync" is enabled, a rollback delete will also delete the equivalent
checkpoint on the standby CF and shuffle the suffixes on the standby CF.
It is not advised to manually delete a rollback checkpoint (for example, using a "file delete" command). If a
rollback checkpoint file is manually deleted without using the "admin rollback delete" command then the
suffixes of the checkpoint files are NOT shuffled, nor is the equivalent checkpoint file deleted from the
standby CF. This manual deletion creates a "hole" in the checkpoint file list until enough new checkpoints
have been created to roll the "hole" off the end of the list.
Default
none
Parameters
latest-rb — Specifies the most recently created rollback checkpoint (corresponds to the file-url.rb rollback
checkpoint file).
checkpoint-id — An id from [1 ..max] indicating a specific rollback checkpoint (where max is the highest
checkpoint allowed/configured). A checkpoint-id of 1 indicates the rollback checkpoint file (at the
configured rollback-location) with "*.rb.1" as the suffix, 2 for file "*.rb.2", etc.
rescue — Deletes the rescue checkpoint. No checkpoint suffix numbers are changed.
rollback-location
Syntax no rollback-location file-url
Context config>system>rollback
Description
The location and name of the rollback checkpoint files is configurable to be local (on compact flash) or
remote. The file-url must not contain a suffix (just a path/directory + filename). The suffixes for rollback
checkpoint files are ".rb", ".rb.1", ..., ".rb.9" and are automatically appended to rollback checkpoint files.
Default
None. A valid rollback-location must be configured before a rollback save is executed.
rescue-location
Syntax no rescue-location file-url
Context config>system>rollback
Description The location and filename of the rescue configuration is configurable to be local (on compact flash)or
remote. The suffix ".rc" will be automatically appended to the filename when a rescue configuration file is
saved. Trivial FTP (tftp) is not supported for remote locations.
Default
None. A valid rescue-location must be configured before a rescue configuration is saved.
