This article contains comprehensive information about backing up Outlooks, however if you prefer video instructions over written articles click the Video Tutorials button below to see how you can back-up Outlook automatically:

Just imagine what would happen if all of a sudden your system would crash and you would lose all your Outlook information. The safest way to protect your data is to create regular backups of your Microsoft Outlook data (emails, calendar entries, contacts, etc.) and keep these on removable media such as external drives, Blu-ray/DVDs, FTP/SFTP remote locations, Amazon S3 or Azure Cloud.

Details:

Almost all of the data for Outlook is stored in .pst files, which means that by backing it up you protect the following information: Emails (in all folders, including archived items), Calendar entries, Contacts, Tasks and Notes. In order to have a complete backup of Outlook data, it is not enough to back up only the .pst files, but the following items too:

• Personal Address Book • Offline Address Book (2010) • Rules • Signatures • Stationery and Templates • Menu or toolbar customizations • Nicknames • Navigation Pane settings (this file includes Shortcuts, Calendar, and Contact links). • Dictionary • Send/Receive settings • Print styles • Custom forms • Registered Microsoft Exchange extensions

Starting Outlook 2010, Microsoft is using the .ost files (Offline Outlook Data file) to store a local copy of the emails. Backing up the OST files is needless.

This is the Microsoft position regarding .ost files: "Maintaining changes to OST files within shadow copies is expensive in terms of space and I/O activity. The time-consuming work at backup time is backing up the OST files as part of the image. Everyday I/O will write to the OST file when Outlook is running. So the backup process will impact the performance on the computer. If the OST changes were kept in shadow copies, then Outlook writes to the OST files is copy on write I/O hit (2 writes, 1 read)every time. Even though we have worked to reduce the impact of copy-on-writes on shadow copies, a heavily churned file such as OST file still cause problems on the computer. In addition, the OST files can be regenerated. We delete OST file from the shadow copy before the image is created. For example, after restoring an OST, the computer detect a new version of the OST file on the computer, it will force you to delete, and the regenerate the local OST file. Therefore, it is still preferable to regenerate an OST file instead of restoring it."

If you still want to backup the .ost files using Backup4all, you need to close Outlook and also disable the "Backup open files" option from Backup Properties->Advanced page. After that you can run the backup.

How to configure an automatic backup for Outlook (2013, 2010, 2007, 2003)

Backup4all is a backup program that lets you back-up Outlook automatically. Basically you just have to define a backup job where you define various settings (such as where to keep the back-up, when to run the back-up, what type of backup to use) and that's it, your Outlook will be backed up regularily (if you choose to schedule it). Here are the steps to follow to create a new backup job that will back-up Microsoft Outlook data:

1. Download and install Backup4all here (if you don't have it already installed): Backup4all download 2. Open Backup4all and select File->New Backup (Ctrl+N). 3. On the first page enter a name for the backup in the Backup Name field. Select a backup destination where you want to save your backup and press Next. 4. On What do you want to backup select Microsoft Outlook and press Next. 5. Select the backup type and decide if you want the backup to be password-protected or not. Click Next. 6. Select how often you want the back-up to run and press Save. The new backup job will appear in the backup list. 7. Press Backup (F6) to start backing up Microsoft Outlook or leave it run when the scheduled date you've set previously will be reached.

Outlook data is stored in “.pst” files. For each mail folder defined in Outlook a .pst file is assigned. These files get quite large if you exchange lot of emails, thus when a small change occurs in a file (e.g. a new email has been received), the entire .pst will be marked as “modified”. When running the backup, the whole file will be backed up as you cannot backup only the changes inside the .pst file. That's why it is recommended to do a full or mirror backup (and not differential or incremental). Also, it is recommended to limit the number of backups in order to save disk space.

How to manually back-up Microsoft Outlook

The easiest way to back-up outlook is using a tool that automates the process as described in the previous section.

Backup limitations for locked or open files

The backup and restore for Outlook works only if you use the same version of Windows and the same version of Outlook on both the backup and restore computers.

Backup4all uses the Volume Shadow Copy service that allows you to back up local open files from NTFS partitions under Windows 7/Vista/XP/2008/2003. Therefore you can back up Outlook without closing it if certain requirements are met: • computer is running Windows 7, Windows 2008 Server, Windows Vista, Windows XP and Windows 2003 • Microsoft Outlook data is not being backed up via the network • Microsoft Outlook data is located on a NTFS formatted partition • the VSS (Volume Shadow Service) is running and is properly configured

If any of the requirements above is not met, Outlook will need to be closed before backing up the data (otherwise files that are in use will be skipped).

Applies to:

• Backup4all 3.x, 4.x, 5.x • Outlook 2003 • Outlook 2007 • Outlook 2010 • Outlook 2013
