BitSilo

BitSilo allows you to back up files to a compressed archive of the .bitsilo or .zip type, i.e. to a single file on disk. Backups can be set for folders or just for specific files, of course you can set time cycles like daily, weekly, monthly backups and also their time. It also allows you to create incremental backups, which saves disk space and only backs up changed files. You can then even search and restore only the files you want in the backup archives. Of course, it also automatically deletes old backups.
