DEB/RPM packages: https://github.com/subuk/bakapy/releases
See comments in /etc/bakapy/... files.
Each backup job has one command. Command is a shell script for collecting data on the server. Command must use function _send_file for send file to storage.
The simplest example:
for d in usr etc root ;do
tar -cf - /$d | _send_file "main/$d.tar"
done

A cron expression represents a set of times, using 6 space-separated fields.
Field name | Mandatory? | Allowed values | Allowed special characters
---------- | ---------- | -------------- | --------------------------
Seconds | Yes | 0-59 | * / , -
Minutes | Yes | 0-59 | * / , -
Hours | Yes | 0-23 | * / , -
Day of month | Yes | 1-31 | * / , - ?
Month | Yes | 1-12 or JAN-DEC | * / , -
Day of week | Yes | 0-6 or SUN-SAT | * / , - ?
Note: Month and Day-of-week field values are case insensitive. "SUN", "Sun", and "sun" are equally accepted.
The asterisk indicates that the cron expression will match for all values of the field; e.g., using an asterisk in the 5th field (month) would indicate every month.
Slashes are used to describe increments of ranges. For example 3-59/15 in the 1st field (minutes) would indicate the 3rd minute of the hour and every 15 minutes thereafter. The form "*/..." is equivalent to the form "first-last/...", that is, an increment over the largest possible range of the field. The form "N/..." is accepted as meaning "N-MAX/...", that is, starting at N, use the increment until the end of that specific range. It does not wrap around.
Commas are used to separate items of a list. For example, using "MON,WED,FRI" in the 5th field (day of week) would mean Mondays, Wednesdays and Fridays.
Hyphens are used to define ranges. For example, 9-17 would indicate every hour between 9am and 5pm inclusive.
Question mark may be used instead of '*' for leaving either day-of-month or day-of-week blank.
