`ccollect` is a backup utility written in the sh-scripting language.

It does not depend on a specific shell, only `/bin/sh` needs to be

Incompatibilities
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
Versions 0.5 and 0.6
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
.The format of `rsync_options` changed:
|
||||
- Before 0.6 it was whitespace delimeted
|
||||
- As of 0.6 it is newline seperated (so you can pass whitespaces to `rsync`)
|
||||
|
||||
You can update your configuration using `tools/config-pre-0.6-to-0.6.sub.sh`.
|
||||
|
||||
.The name of the backup directories changed:
|
||||
- Before 0.6: "date +%Y-%m-%d-%H%M"
|
||||
- As of 0.6: "date +%Y%m%d-%H%M" (better readable, date is closer together)
|
||||
|
||||
For the second change there is no updated needed, as XXXX- is always before
|
||||
XXXXX (- comes before digit).
|
||||
|
||||
|

|
||||
Versions 0.4 and 0.5
|
||||
