Although the low-level database used in PowerMail has proven very reliable over time (in fact, almost as reliable as a personal computer database can be) a low-level disk error caused by a damaged disk block is a risk that can never be neglected. As such, we recommend making periodic backups of your PowerMail files folder.
Before backing up your PowerMail files folder, it is suggested that you compact your database using the File / Database / Compact database menu item. See "Moving or copying your database to another machine, or to another drive" below for more informations.
If you are short of disk space for your backup, you can omit the enclosed file named "Message Database Index" since this is only used to find by content and can be reconstructed at any time.
In addition, consider making periodic backups using the Export function using the LDIF format for the address book and either the PowerMail Exchange, Netscape/Mozilla or Unix mailbox file formats: as these formats are all text-based, this guarantees your ability to access your backups at any time without relying on a proprietary format.
Moving or copying your database to another machine, or to another drive
Before you copy or move your PowerMail files folder to another machine, or to another drive, it is suggested that you compact it, using the File / Database / Compact database menu item. When you compact your database, some additional verifications are performed, and this will insure that the attachments references are up to date. These verifications are also performed when you enable "Verify the consistency of database records" in the PowerMail First Aid window (see the Troubleshooting section).
