differential backup syntax please #108

Closed tukoz closed 9 years ago

tukoz commented 9 years ago

Hi, For differential backups the wiki says

$ cyphertite -B 110522_usr_local_bin_1.ct -cvf 110523_usr_local_bin_2.ct /usr/local/bin

I have no idea on how to use this example for automation (daily or else) in eg. crontab?

Here's what I have atm before reading some more precision. $ crontab -l

23   13    *    *    *   <path_to/user_incremental.daily>

The user_incremental.daily> executable bash script:

 ct -E /home/kozaki/.cyphertite/exclude -cHf <md_filename>1.ct

And ~/.cyphertite/cyphertite.conf:

ctfile_remote_auto_incremental  = 1                                                
ctfile_differential_allfiles    = 1                                                
ctfile_max_incrementals = 7                                                        
ctfile_cull_keep_days = 30

If doing automatic incremental backups, you use the same command you would use for creating a full backup. Cyphertite will create a full backup initially, then ctfile_max_incrementals incremental backups, before doing another full backup.

Aha thank you sir! Maybe the wiki would gain clarity with this clarification. This way, backups ie ctfiles older than ctfile_cull_keep_days will be removed, unless their content is still referenced in newer (less than 30 days in this case) ctfiles. Correct?
