Keeping Keepass in Sync between PC and Adroid Clients via Owncloud

1. Try - using KeePassDroid

No sync features at all


2. Try - using keypass2android and owcloud-sync-folder

  1. Put keepass.kdbx on Owncloud folder
  2. Open on Owcloud Client and choose "keep in Sync"

    +Straight forward
    -  Have to open Owncloud-Client on Android before opeining to make sure DBs are synced
    ~ Not sure if sync works when file is open on moret than one clients

 3. Try - using keypass2android and webdav access

  1. Open your kdbx-file via WEBDAV link - e.g.

    + no need to sync - direct acces to remote file
    - error messages (transactions) when editing file from 2 sides - can be suppressed by disabling option "Filetransactions" keepass2android - be careful!! Make sure you have backups!

 For me 3. solution works fine now - always make sure to close and safe - keep in mind, where the last changes were done

Enable EPEL (yum install epel-release)

optional: yum install bash-completion mc

yum install backuppc

chkconfig backuppc on

service backuppc start


Open Firewall-Port 80

firewall-cmd --zone=public --add-port=80/tcp 

Edit /etc/httpd/conf.d/BackupPC.conf, so that your client access is allowed

Most comfortable way to migrate files between 2 servers is creating a mount via sshfs.

yum install sshfs  (fuse-sshfs from EPEL on Redhat + derivates)

sshfs root@10.0.1.x:/var/www/ /mnt/ -o reconnect -C -o workaround=all
