Problem this snippet solves:
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
