and a command-line interface. The application includes the following features: * ZIP/ZIP64 compression * AES 128 & AES 256 encryption * Backup filters (by extension, subdirectory, regular expression, size, date, status, usage) * Incremental backup, differential and full backup support *

Delta Delta commonly refers to: * Delta (letter) (Δ or δ), a letter of the Greek alphabet * River delta, at a river mouth * D ( NATO phonetic alphabet: "Delta") * Delta Air Lines, US * Delta variant of SARS-CoV-2 that causes COVID-19 Delta may also ...

support ( SSL/ TLS in both implicit and explicit modes) * SFTP support (with password or certificate authentication) Areca also provides all tools needed to handle your archives: * Backup * Archive recovery (with or without deleted files); entire archives or single files can be easily recovered * Archive merge: contiguous incremental archives can be merged into a single archive to save storage space * Archive deletion * History explorer: different versions of a given file can be browsed and restored * Archive explorer: files can be searched among your archives Storage modes Areca can handle multiple storage modes: * Standard: It is the default mode, which is recommended for most users: If you choose this storage mode, a new archive will be created for each backup. All new or modified files since the last backup will be stored in this archive. *

: This mode is recommended for advanced users only: If you choose this storage mode, a new archive will be created for each backup. All modified *parts* of files since the last backup will be stored in this archive. This mode is particularly useful if you are handling large files. * Image: If you choose this storage mode, a unique archive will be created and updated at each backup. Backup types Areca can handle the following types of backups: * Full Backup: When a full backup is performed, ALL files are stored in your archive (whether they have been modified or not). * Incremental backup: When an incremental backup is performed, only the files which have been modified since the last backup are stored in your archive. *

Differential backup A differential backup is a type of data backup that preserves data, saving only the difference in the data since the last full backup. The rationale in this is that, since changes to data are generally few compared to the entire amount of data in t ...

: When a differential backup is performed, only the files which have been modified since the last FULL backup are stored in your archive. Areca uses the file's size and last modification time to detect modified files. If one of these attributes is modified (whatever its value is), the file is flagged as modified. This allows a fast detection of modified files. Areca is downloadable pre-packaged for

Limitations

* Areca Backup does not have a built in method of handling automated backup creation for Windows-based operating systems. The user is required to configure a backup strategy using an included Wizard, which consequently creates a collection of bat files required to be manually added to the Windows Task Scheduler. * Areca Backup does not support VSS (Volume Shadow Copy Service) and cannot backup files that are locked by other programs, but there are plugins for Areca that do (like ArecaVSS)
