Hello all,
We have created our own class extending
info.magnolia.module.backup.commands.BackupCommand, because we don't want dump
directories with timestamps in them, but just a single directory called
'current' with the latest backup. Our class overrides the execute() method like
this:
----
@Override
public boolean execute(Context ctx) {
return super.execute(ctx) && post();
}
private boolean post() {
return deleteCurrentBackup() && renameMostRecentBackupToCurrent() &&
deleteOtherBackups();
}
----
This all seems to work fine, but after the backup is completed loading
resources from DMS starts to break. In the logs we get stacktraces like the one
below. DMSDownloadServlet starts reporting 'error during download', which is
ultimately caused by a backup (!) file no longer existing. I have no idea why
it would need to be able to read this file in the backup, but my guess is that
our renaming of the backup directory after it is done is causing this.
* Why does a missing backup file cause this DMS error?
* How could we change our backup strategy to not interfere with this?
Nils Breunese.
