With the recent resurgence of variants of the CryptoLocker ransomware virus, including CryptoWall, we remind clients how critical it is to make sure all key elements of your data are properly and regularly backed up.
For instance, several clients using Tabs3/PracticeMaster and Worldox were hit by the nasty CryptWall bug. They were using the Backup utility within the Tabs3 database, and then copying the backup files to an external or online backup destination.
Unfortunately, not all subdirectories within the Tabs3 directory are backed up automatically using the built-in Backup utility. Not backed up are the Reconciliations and Statements directories.
These directories contain PDF files of your historical bank reconciliations and statements sent via email, but are not backed up with the regular data files. If these are not separately backed up to a local or off-site destination, they cannot be restored properly after a virus attack. Every firm should make sure all of its data is being backed up. Don't rely solely on the default selections in built-in backup utilities or separate backup software programs.
Also, any backup system that relies on human intervention is going to fail. Use a local external hard drive as a secondary backup system so that lost or corrupted files can be restored faster than with an online backup. However, every firm should have at least one Cloud-based backup system. That system will do real-time automatic backup. To avoid the various Crypto ransomware problems, only use backup systems that do versioning. That way, earlier unencrypted versions of files can be restored even if the backup sysstem runs a backup of the newly infected/encrypted files.
