21st Century Accounting Help - System/Company


Use the System/Company/Checkpoint to set aside a copy of your company data at any point in time. The system maintains a compressed copy of all the data you have ever entered into 21st Century Accounting. All the data is stored as "batches." Checkpoint puts a copy of this file wherever you choose. If you become aware of a problem with the data you're currently working with, you can recover the company (with System/Company/Recover) from a Checkpoint file, batch-by-batch, if appropriate.

The compressed file that contains all the data you have entered into 21st Century Accounting is named posted.cpz. It resides in the batch folder in the company data folder.

The copy of the posted.cpz file that Checkpoint creates uses the company name as the default filename and has an extension of .ckp. The file date and time of the .ckp file reflects the date/time of the last posted batch (the last time posted.cpz was updated.)

For additional safety (and to eliminate the need to know which batches might be bad), you can use the rotation method of making backups. With this method, you rotate your Checkpoint (or other backup) location or media by recycling the oldest location. (Put the Checkpoint file or other backup on a network server, removable disks, or a flash drive to avoid losing your data if your hard drive fails.) The rotation method ensures that a substantial portion of yoru data is protected, even if some time passes before you detect that your current data is damaged. Two examples of the rotation method follow:

  • Making three backups for a five-day work week, make a backup on Monday, a second backup on Tuesday, and a third backup on Wednesday. On Thursday, reuse Monday's backup location to make your daily backup. On Friday, reuse Tuesday's location. On the next Monday, reuse Wednesday's location.

  • Making five sets of backups for a five-day work week, back up at the end of every work day. On each Monday, reuse last Monday's backup location to make your daily backup. On Tuesday, reuse last Tuesday's location, and so on.
Following the scenarios above on a network server, create three or five subdirectories with appropriate names for rotating the backup location. If on removable media, label, number, and date your backups so that you can recycle the oldest media.
