In continuation with my previous article EBS Snapshot using Backup_Monkey<\/a>, we have discussed one issue associated with BackUp Monkey utility.<\/p>\n

The issue was that it use’s “BACKUP_MONKEY” prefix and tag the snapshot with this prefix.<\/em><\/p>\n

\"Blog<\/a><\/p>\n

As you can see in the Description, BACKUP_MONKEY prefix is used. So this create’s a redundancy while finding the exact snapshot, as every snapshot is tagged with this same format. But we want a snapshot with the name same as “Instance Name” so that we can identify the snapshot easily. To do so we have to modify the source code.
\nbackup<\/span>-monkey<\/code> command uses \/usr\/local\/lib\/python27\/dist<\/span>-packages\/backup_monkey\/core.<\/span>py<\/span><\/strong><\/p>\n

File<\/span> to be modified: \/usr\/local\/lib\/python27\/dist<\/span>-packages\/backup_monkey\/core.<\/span>py<\/span><\/p>\n

Locate line number 29 and comment it out
\nself<\/span>.<\/span>_prefix='BACKUP_MONKEY' <\/code><\/p>\n

and<\/span> Replace it with
\nself<\/span>.<\/span>_prefix=self.<\/span>_conn.<\/span>get_all_instances(<\/span>) <\/code><\/p>\n

self<\/span>.<\/span>conn.<\/span>get_all_instances(<\/span>) will return all instances Reservation id<\/strong><\/p>\n

Now, Replace original code<\/span> in “core.<\/span>py<\/span>” with this following code.

\n62 \u00a0\u00a0\u00a0\u00a0return True<\/code><\/p>\n

We added this line<\/p>\n

description_parts=[<\/span>self.<\/span>_prefix[<\/span>i<\/span>].<\/span>instances[<\/span>0].<\/span>tags[<\/span>'Name']] <\/code><\/p>\n

This is basically extracting the Tag Name associated with the Reservation Id extracted above.<\/p>\n

Next part is to modify the remove_old_snapshots(<\/span>)<\/strong> section.<\/p>\n

Below code is<\/span> used for removing snapshots with the extracted Tag Name.

\n76 \u00a0\u00a0\u00a0\u00a0 if not snapshot.description.startswith(self._prefix[j].instances[0].tags['Name']):
\n77\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 log.debug('Skipping %s as prefix does not match', snapshot.<\/span>id)
\n78\u00a0\u00a0\u00a0\u00a0 continue
\n79\u00a0\u00a0\u00a0\u00a0 if not snapshot.<\/span>status == 'completed':
\n80\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 log.debug('Skipping %s as it is not a complete snapshot', snapshot.<\/span>id)

\n82\u00a0\u00a0\u00a0\u00a0 j=j+1
\n<\/code><\/p>\n

We are done with the modification. Lets<\/span> Test it out.<\/p>\n

This is my Instance with Tag Name “Testing Instance”.<\/p>\n

\"Blog<\/a><\/p>\n

Lets<\/span> run
\n $backup-monkey --region us-west-2<\/strong> <\/code><\/p>\n

\"Blog<\/a><\/p>\n

Now you can see below the difference between the two snapshot<\/span>. One with “BACKUP_MONKEY” which was the previous one, other with “Testing Instance” name<\/p>\n
