How to backup files

PeaZip is a free cross-platform backup and file archiver utility that provides an unified portable GUI for many Open Source technologies like 7-Zip, FreeArc, PAQ, UPX... free alternative to WinRar, WinZip and similar proprietary software.
- Create 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, ZIP files
- Open and extract ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX files and more,
over 180 archive types supported
Features of PeaZip includes:
archives opener and extractor, batch creation and extraction of multiple archives at once, convert files, create self-extracting archives, split and join files, secure encryption with two factor authentication, encrypted password manager, secure deletion, find duplicate files, calculate hash and checksum, save and export backup tasks definition as scripts.

What is data backup purpose

how to create backup

Backup is the process of creating security copies of the data to protect against unexpected data loss (device failure, unwanted modifications), on demand (i.e. before committing significant changes to the system, or to user's files) or, more often, as scheduled task on a regular basis, commonly during night hours or anytime the system is not being actively used, in order to reduce the impact of the operation on performances.

While live copies of the data (as mirroring or some RAID configutarions providing data redundancy, i.e. RAID5), guarantee ability to promptly recover from som cases of data loss (i.e. a faulty disk drive) in some configurations even without interrupting the work, only a backup copy allows to protect data against unintentional deletion (even secure data deletion) or undetected corruption, providing the ability to restore previous saved copies of the data.

Backup software

Specific backup applications (as Areca Backup, Bacula, Cobian BackupBackup freeware, Symantec Backup Exec, Norton Ghost, etc), may feature abilities out of the scope of PeaZip project, which is more oriented to general purpose archiving and file management, i.e. differential backup which is the process of saving only a copy of the data actually changed since the last backup task, or low level disk copy routines to physically clone the hard disk - more common in software specifically meant for cloning disk images (as Acronis True Image, Nero, PowerIso, Winimage, Apple Disk Copy).

However, PeaZip has different advantages due to its nature of multi purpose software, featuring many functions useful for backup operations.
In example, one of the areas PeaZip is focused in is bridging the gap between scripting and GUI application, the program being able to save file compression operations from GUI to script files.
In this way the definition of a backup task can be easily exported as a command line and used in any system scheduler, or in third party programs and scripts: Add > Console > Save job definition creates a plain text file containing the job definition, saved by default in a "Scripts" subfolder in PeaZip's configuration path, which is unique for each user.
In the same way it can be saved and scheduled the definition of ìextraction tasks, i.e. in order to restore / recover backup files and folders programmatically, or even a file conversion operation in order to change the backup file format to make it readable on different systems if needed.

PeaZip features strong encryption protocols, (i.e. WinZip AES256 AEaes encrypted zip encryption for ZIP files; 7-Zip AES2567zip encryption specs encryption for 7Z files; AES, Twofish and Serpent for ARC files), including optional encryption of TOC (table of content, list of contained files and folders) of the archive in order to protect and keep private the content of the backup archive, including file and directories names, until the correct password is provided.

Two factor authentication is optionally supported for all archive format using encryption; this improves the security of the encryption using a key file along the password.

backup and restore files

Decrypting the archive file will need, if two factor authentication is used, both to know the password and to have the key file.
PeaZip also comes with an encrypted password manager to help safely managing multiple passwords.

Backup usually involves copying large quantities of files, making in some cases use of strong compression algorithms impractical: for those cases PeaZip supports fast compression algorithms, or even file storing without compression, but it also provides state of art strong compression algorithms when this need does not apply, in order to save most disk space it is possible (to reduce the cost of storing more copies if the backup over the time), or to reduce the size of the output in order to reduce bandwidth usage when backup is not stored locally (i.e. on SAN/NAS).

PeaZip also allow to split the output file in volumes of a given size (file spanning), so each part can be stored in smaller back up units if needed.

As general purpose file archiver application, PeaZip can also easily add / remove data from existing archive, and update date inside existing archives - policy can be set to replace only older data (standard update command), freshen archive only adding new version of files already featured in the archive, or sync with disk keeping only the archive content matching with current live data.
