List the files in your most recent backup zpaq list backup.zpaq For backups, -method 1 is recommended, although -method 2 is nearly as fast. Using -method 0 does not compress any data. Using the most extreme (and slowest) compression (default is 1): zpaq add backup.zpaq -method 5 The -key option encrypts the backup with AES-256. On the other hand, once the initial backup has been done, incremental backups only need very little memory, and are very fast. By default, zpaq cuts files into blocks that are about 64 kilobytes big, and it stores only the blocks the have not yet been encountered by the program.ДЄs a backup software, zpaq has a disadvantage - it does not allow you to delete old backups. By default, the add options only adds files with a newer date, or with a changed file size. It can be used for incremental backups, and you can revert to any previous file version.

Old versions of files on the server are stored as changes from the current version, minimising the storage space required on the server.ДЇiles are the server are also compressed to minimise their size.

Only changes within files are sent to the server, just like rsync, minimising the bandwidth used between clients and server.

A backup daemon runs on systems to be backed up, and copies encrypted data to the server when it notices changes - so backups are continuousДЄnd up-to-date (although traditional snapshot backups are possible Network (such as the Internet), or where the server is in an This makes it ideal for backing up over an untrusted The server is trusted only to make files available when they are required - all data is encrypted and can be decoded only by the

All backed up data is stored on the server in files on a filesystem - no tape, archive or other special devices are required.
