bug-fix¶

at least in our environment sending mails does not work out of the box. mail.php needs to be fixed. See also configure outgoing mail

Client Integration¶

improve performance¶

you may look up the performance thread in the owncloud-forum https://forum.owncloud.org/viewtopic.php?f=8&t=10692

setup cron.php-job

to check the logs of owncloud more easily you may want to make a symbolic link to the admin-files

ln -s /var/www/html/owncloud/data/owncloud.log /var/www/html/owncloud/data/admin/files/owncloud.log

h1. Migrate from SQLite3 to MySQL

Backup/Restore¶

a very interesting article is https://wiki.amahi.org/index.php/Backup_and_Recovery_of_ownCloud

Backup DB¶

SQLite¶

While SQLite-DB consists of just one file, you shouldn't just copy the file. It might be corrupted by doing so.

If you want to copy the DB-file you might want to (taken from http://stuvel.eu/blog/55/safely-copy-a-sqlite-database)

shell$ sqlite3 some.db
sqlite> begin immediate;
<press CTRL+Z>
shell$ cp some.db some.db.backup
shell$ exit
sqlite> rollback;

the other way may be dumping the DB. This is easily done by

sqlite3 sample.db .dump > sample.bak

based on the rsnapshot-backup-script for postgresql following script might be invoked by rsnapshot

# by Nathan Rosenquist <nathan@rsnapshot.org>
# 
# This is a simple shell script to backup a SQLite database with rsnapshot.
#
# The assumption is that this will be invoked from rsnapshot and also that it
# will run unattended.
#
# This script simply needs to dump a file into the current working directory.
# rsnapshot handles everything else.
##############################################################################

umask 0077

# backup the database
/usr/bin/sqlite3 /var/www/html/owncloud/data/owncloud.db .dump > owncloud_dumpall.sql

# make the backup readable only by root
/bin/chmod 600 owncloud_dumpall.sql

Backup Files¶

as the "files" are not stored in the database but in the filesystem you also need to make a backup of those. Maybe the easiest way is to completely save the whole owncloud folder-structure via rsnapshot.

Following line may be added to rsnapshot.conf

backup         /var/www/html/owncloud           localhost/
backup_script  /usr/local/bin/backup_sqlite.sh  localhost/sqlite/

h2. Restore DB

SQLite¶

mv sample.db sample.db.old
sqlite3 sample.db < sample.bak

mount web_dav¶

This requires davfs2-package

mount.davfs -o dir_mode=775 https://example.com/owncloud/remote.php/webdav /mnt/owncloud_dav/
