Available job types

WinZip's Job Wizard provides five predefined Job Types plus a Custom job type. The first two predefined types, Normal and Update, may be familiar to you as Zip file options. The other three job types; Full, Differential, and Incremental; are standard backup types. Carefully consider these different job types in order to determine the appropriate backup strategy for your needs.

Example backup strategies

The examples below are some strategies that you could use for backing up data. Other options exist. You would need to choose a strategy that fits your needs and works for you.

Safety note: in all four strategies, you would also want to keep the older of Full Data Backups off-site in case of an on-site disaster.

Strategy 2: If your incremental backup (Zip file 3) is damaged, you have only lost the data since the last Friday backup.

Strategy 3: If any incremental backup is lost or corrupt, you will still have all the changes from the other incremental backups, and you only lose the data from the one Incremental Backup.

Strategy 4: If Zip files 3, 4, or 5 become lost or corrupt and Zip file 6 is still good, you haven't lost any data. If Zip file 6 becomes lost or corrupt, then, assuming Zip file 5 is still good, you will only lose the data from Thursday.
