Stiati de Mathusalem? In special cei nemultumiti de Time Machine.
Din ce poate face:
It supports a wide range of destinations: local drives, iDisk, WebDAV, AFP, FTP, SFTP or Amazon S3
It can generate archives in various formats: sparse or compressed .dmg and CPIO or ZIP archives
It generates fully self-contained backups i.e. data and settings which makes it possible to access them from any machine or even relocate them
It can restart a download or upload that failed or was cancelled by the user without having to restart the entire backup
It runs in low-priority mode on your machine so it doesn’t hang your CPU or hard drive
It runs only when necessary (it is managed by launchd like other system services)
It is fully open-source which means no proprietary file formats (backup data files are plain XML)
It stores passwords in the Keychain
It reports detailed information on the backup progress
The command line tool version can be integrated in existing tool chains or used with launchd
Din ce nu poate face:
It only cares about modifications of the actual file content, not of its attributes like access permissions
To determine is a file has changed, it only looks at its modification date
It does not follow symlinks
It does not preserve owner and permissions on files or directories
It does not preserve extended attributes on directories (but of course preserves them on files)
The initial backup requires as much extra space on the boot volume as the total size of the data being backed up
You cannot “prune” old incremental backups
It is not capable of splitting individual files when creating segmented backups
