F5 Archiver Ansible Playbook
Problem this snippet solves: Centralized scheduled archiving (backups) on F5 BIG-IP devices are a pain however, in the new world of Infrastructure as Code (IaC) and Super-NetOps tools like Ansible can provide the answer. I have a playbook I have been working on to allow me to backup off box quickly, UCS files are saves to a folder names tmp under the local project folder, this can be changed by editing the following line in the f5Archiver.yml file: dest: "tmp/{{ inventory_hostname }}-{{ date['stdout'] }}.ucs" The playbook can be run from a laptop on demand or via some scheduler (like cron ) or as part of a CI/CD pipelines. How to use this snippet: F5 Archiver Ansible Playbook Gitlab: StrataLabs: AnsibleF5Archiver Overview This Ansible playbook takes a list of F5 devices from a hosts file located within the inventory directory, creates a UCS archive and copies locally into the 'tmp' direcotry. Requirements This Ansible playbook requires the following: * ansible >= 2.5 * python module f5-sdk * F5 BIG-IP running TMOS >= 12 Usage Run using the ansible-playbook command using the inventory -i option to use the invertory directory instead of the default inventory host file. NOTE: F5 username and password are not set in the playbook and so need to be passed into the playbook as extra variables using the --extra-vars option, the variables are f5User for the username and f5Pwd for the password. The below examples use the default admin:admin . To check the playbook before using run the following commands ansible-playbook -i inventory --extra-vars "f5User=admin f5Pwd=admin" f5Archiver.yml --syntax-check ansible-playbook -i inventory --extra-vars "f5User=admin f5Pwd=admin" f5Archiver.yml --check Once happy run the following to execute the playbook ansible-playbook -i inventory --extra-vars "f5User=admin f5Pwd=admin" f5Archiver.yml Tested this on version: 12.11.8KViews2likes1CommentUCS saving process failed.

Hi all, Often I've been scouring the devcentral fora and codeshares to find that one piece of handywork that will drastically simplify my automated backup needs on F5 devices. Based on the works of Jason Rahm in his post "Third Time's the Charm: BIG-IP Backups Simplified with iCall" on the 26th of June 2013, I went ahead and created my own iApp that pretty much provides the answers for all my backup-needs. Here's a feature list of this iApp: It allows you to choose between both UCS or SCF as backup-types. (whilst providing ample warnings about SCF not being a very good restore-option due to the incompleteness in some cases) It allows you to provide a passphrase for the UCS archives (the standard GUI also does this, so the iApp should too) It allows you to not include the private keys (same thing: standard GUI does it, so the iApp does it too) It allows you to set a Backup Schedule for every X minutes/hours/days/weeks/months or a custom selection of days in the week It allows you to set the exact time, minute of the hour, day of the week or day of the month when the backup should be performed (depending on the usefulness with regards to the schedule type) It allows you to transfer the backup files to external devices using 4 different protocols, next to providing local storage on the device itself SCP (username/private key without password) SFTP (username/private key without password) FTP (username/password) SMB (using smbclient, with username/password) Local Storage (/var/local/ucs or /var/local/scf) It stores all passwords and private keys in a secure fashion: encrypted by the master key of the unit (f5mku), rendering it safe to store the backups, including the credentials off-box It has a configurable automatic pruning function for the Local Storage option, so the disk doesn't fill up (i.e. keep last X backup files) It allows you to configure the filename using the date/time wildcards from the tcl [clock] command, as well as providing a variable to include the hostname It requires only the WebGUI to establish the configuration you desire It allows you to disable the processes for automated backup, without you having to remove the Application Service or losing any previously entered settings For the external shellscripts it automatically generates, the credentials are stored in encrypted form (using the master key) It allows you to no longer be required to make modifications on the linux command line to get your automated backups running after an RMA or restore operation It cleans up after itself, which means there are no extraneous shellscripts or status files lingering around after the scripts execute I wasn't able to upload the iApp template to this article, so I threw it on pastebin: http://pastebin.com/YbDj3eMN Enjoy!

We are currently facing issue to run archive process on all VCMP on c2400 chassis. f5 identified this to be an bug and provided an hotfix but we are unable to apply the fix due to maintenance window. We are running behind on backup for months now. Is there any other manual process that we can run a archive process so we can restore the box in case of any crash scenario ?489Views0likes10CommentsBackup iApp questions
I'm fairly new to Big IP. I'm trying to automate backups of the config. We are running 11.4.1. I found an iApp (https://devcentral.f5.com/wiki/iapp.configuration_backup_scheduler_v11_2.ashx) and it seems to be working well. My problem is that it pushes the tar file to a direcoryton the Big IP device. How can I automate getting the backup files off of the device? Doesn't look like WinSCP has anything for scheduling/automating file copies. I'm not real Linux savvy but I know enough to get but. Need some guidance here.
