ZIP Download

[WolfgangEibner]

Implement ZIP Download

Should be clarified:

• path where to store zip files
• access from frontend to zip files
• delete old zip files after an specific amount of time (cron job)

[ghost]

Note: The zip plugin doesn't need any input parameters. The list of required inputs will therefore be empty. In general: The frontend should skip to the next web page, if a plugin doesn't need any inputs (a call to postAuth can be omitted in these cases)

ZIP-Plugin is now deployed on dev02, copying the zip files to /tmp/backups/{userId}/{backupfilename}-{timestamp}.zip

@WolfgangEibner / @fetzig: Please specify the destination folder for the frontend on dev01 - I'll use the same as on dev02 for now.

@keros: I would also like to test the sftp feature. Please provide a ssh certificate + correct paths to copy to. To do this, we have to configure the zip plugin's zip.properties file (src/main/resources/zip.properties) and rebuild it:

# {0} ... the user id
temporaryPath = /tmp/backups/{0}/
# note: If isRemote is true, the zip file will be copied to a sftp destination. 
isRemote = true
# {0} ... the user id, {1} ... the filename of the zip
remote.target = /tmp/backups/{0}/{1}
# {0} ... the user id
remote.directory = /tmp/backups/{0}/
remote.host = openrc2
remote.port = 22
remote.user = root
# maybe we want to use a different key here
ssh.key = /root/.ssh/id_rsa

These settings have been copied from the discmailing plugin.

Deployed and tested local zip file creation on dev01.

You can use the "/root/.ssh/id_rsa" key file on the server. The server can now ssh to itself with this keyfile.

Place the files on "/data/backmeup-frontend-backupfiles" or something like this. Don't forget to change the "remote.host" to "localhost".

Ok, I just tested this on dev01. Files will be placed via sftp on localhost /data/backmeup-frontend-backupfiles/{userId} after a zip backup job finished.

ZIP-Plugin working as follows:

• All files given by the Storage instance will be zipped to a temporary location
• If "isRemote" has been set to true, the temporary zip file will be copied via sftp to a remote directory.

dev01 settings: ZIP-Backups will be copied to /data/backmeup-frontend-backupfiles/{userId} as proposed by keros.

Remaining steps:

• Display backup files within frontend.
• Implement a cron job which deletes old backups.

[keros]

Added cronjob to "bmu-dev01"

00 05   * * *   root     find /data/backmeup-frontend-backupfiles -type f -mtime +1 -exec rm {} \;

Files older than one day get now deleted

Closing because only thing left is listing available downloads in UI. Created an extra issue for this (see above).
