iPad Disaster Recovery: Backup Procedures for iPads
One of the core responsibilities of any IT Professional is to make sure that data is there when and where the user needs it. Disaster recovery is the process of guaranteeing we meet this responsibility under any and all circumstances. When using an iPad in an enterprise, disaster recovery of its data is an important function for an IT administrator to master. The great news is – the process is simple and quick to implement.
The disaster recovery process for an iPad can be broken into three phases:
- Back up the data
- Wipe the device
- Restore the data
Phase 1 – Backing up the data will be the focus of this article. I will cover wiping and restoring the device in the coming weeks.
Backup Procedures for iPads
Backing up the iPad is the first and most critical step in iPad disaster recovery. Without a good, timely backup, the data recovered is at best less valuable because it is out of date or incomplete. At worst, the recovered data is non-existent because the data is missing or the backup is unusable. Either of these conditions is unacceptable, so to avoid them it is important to set up the iPad to perform regular backups and perform manual backups when necessary.
There are a few choices when it comes to how to back up an iPad:
- Perform backups through iTunes on a PC or Mac
- Backup wirelessly to iCloud
- Perform backups using another tool such as Apple Configurator or a third-party MDM solution
Today we will look at the first two options and cover the MDM process options in future articles.
Performing an iPad Backup Using iTunes
iTunes backups are completed when a device is hooked up to a PC or Mac that iTunes is running on. This is an automatic part of the sync process and does not require any special user action.
Enabling Encryption of iPad Backups
In an enterprise, data security is a critical concern. iTunes enables enhanced backup security through encryption of its backup files. Without a doubt, enterprises should always take advantage of this.
You can easily turn the option on in iTunes by clicking the device, selecting the Summary Tab, and checking the box for Encrypt iPad Backup. iTunes will then prompt you to enter a password to protect the encrypted backup with.
- Create a Basic Configuration Profile for iPhone or iPad
- Create an Exchange ActiveSync Configuration Profile for iPhone or iPad
Performing an iPad Backup Using iCloud
With the advent of iCloud, the possibility to back up or restore an iPad from anywhere at almost any time became a reality. All that is required to back up to iCloud is Internet access from the iPad, an iCloud account, and enough storage in the account to hold the backup. A user can create a free iCloud account getting 5GB of storage at no cost. You can purchase additional storage if needed. You can create a free iCloud account here: https://www.icloud.com/.
After creating and setting up an iCloud account on the iPad, enabling iCloud backup from this point takes just four finger taps. It is as simple as this: From the Home screen, tap the Settings icon. Next, tap the iCloud option under Settings.
Data Encryption with iCloud
iCloud uses a number of industry best practices to protect the security of user data. For example, all data transferred between the iPad and iCloud is encrypted. Even so, all enterprises should carefully consider whether iCloud use meets their organization’s security policies.
A couple of sticking points to consider about iCloud use in the enterprise:
- Some data, such as email, is not stored encrypted on iCloud’s disks. On top of that, Apple can decrypt even the encrypted data. This means that potentially, an Apple employee could view any data stored on your iCloud.
For some organizations, these issues will not be a problem; for them, iCloud can be a great tool. For others, the issues above are deal breakers and prevent iCloud use in their enterprise.
The backup processes that we went over above will not archive music or apps. On the upside, this keeps backup sizes down, allowing for less storage infrastructure and shorter backup times. These benefits come at the cost of longer restore times that may or may not affect an enterprise.
After a restore, music resynchronizes through the iTunes music library on the PC or Mac. Without access to the PC or Mac, the Music is lost. iCloud takes care of re-syncing music only if iTunes Match is subscribed to and enabled. No iTunes Match, no restored music from iCloud.
While app settings are included in backups, the apps themselves are not. Apps download from the app store automatically after the restore finishes. Depending on the app and the iPad’s Internet connection, it might take hours before the app is once again useable.
These methods allow IT to protect iPad data by creating timely, reliable backups. Regardless of the method selected, both pros and cons exist. IT Administrators must consider what option best aligns with their enterprise policies, goals, and environment.
