Backup strategy

Wolverine

The table below list the shared folder of Wolverine and how they are backed up to Mystique.

Shared folder	Backup strategy
family	Drive ShareSync
homes	Shared Folder Sync (=rsync), daily, 2.05am (encryption and block-based)
music	Drive ShareSync
NetBackup	NONE (empty)
photo	Drive ShareSync
video	Drive ShareSync

Notes:

• Wolverine acts as the client, it uses then Drive ShareSync.

• The Drive ShareSync is disabled during standard hour. It is enabled from 02.00am to 03.00am.

• Mystique acts as the server, it uses then Drive Server.

• Mystique automatically wakes up during backup time (from 02.00am to 03.00am).

• Drive ShareSync is actually a module of Drive Server. See Synology page for setting up.
• Note: Deletion are not detected when Drive ShareSync is off on the client.

• As a result, deleted files will be restored. This is kinda nice feature, but it means we must think to enable the Drive Server service first before doing some clean up...

• We use rsync to sync homes, that contains the backup, to avoid that deletion issue.
• Because we use rsync to sync the homes share from Wolverine to Mystique, the home service on Mystique must be disabled.

Mnemosyne

The table below list the shared folder of Mnemosyne and how they are backed up to Mystique.

Shared folder	Backup strategy
homes	NONE
movie	Shared Folder Sync, manually
music	NONE (empty)
NetBackup	NONE (empty)
photo	NONE (empty)
video	NONE (empty)

Mystique

On the mid-term, Mystique will be entirely replicated to a remote NAS via internet. For now, we have the following shares and backup strategy.

Troubleshoot

Sync issues with CloudStation - Wolverine

Family

• Some files missing, but in the exclude list (Thumbs.db, *.tmp, *.swp, *.lnk, desktop.ini).
• Some file missing that should not (~500MB:

• Files in Program Files folder.

There is no fix for that [1]. Only solution is to rename the folder or zip it.
