Issue/Introduction

Presents commands with examples how to perform manual backup/restore of the VAP image and XOS configuration.

Cause

Depending on situation and requirements it might be feasible to archive just one of the VAP images instead of the whole VAP-group including common folder.

Below are presented commands with examples how the backup and restore might be performed manually.

Resolution

To perform backup of all files for a specific VAP, below command might be used from CPM root shell level:

# cd /tftpboot/<vapgroup_index>
# tar --one-file-system -cjvf <path_to_the_created_file> ./


This command might be run with lowest priority by using "nice -n 19 <command>" command.

Below is example which tars and compresses files from "fw_1" VAP which is part of "fw" vap-group

# mkdir /tftpboot/tmp
# cd /tftpboot/fw_1
# nice -n 19 tar --one-file-system -cjvf /tftpboot/tmp/fw_1_20121003.tbz ./


Please note that the archive file created with above command should be stored on the file-system where's enough space for it, hence please verify free space prior performing backup.

Each vap-group besides images for each VAP, named "<VAPGROUPNAME>_<INDEX>" has "<VAPGROUPNAME>_common" image which is backed up when using archive_dir tool delivered on newer XOS releases.

Once files are created should be off-loaded to external system.

To restore earlier tared and compressed files, below steps should work:
# cd /tftpboot/<vapgroup_index>
# tar xjvf <path_to_the_created_file>



To backup XOS configuration, the file might be stored in flat format and then imported easily.

CLI# copy running-config -flat <path_to_file>

Configuration stored in flat format might be then easily imported on fresh XOS using execute command.

Should there be any additional changes/patches performed directly on file-system of CPM these should backed up as well using i.e. tar command.
