[mattheworiordan]

When trying to install this package following the Ubuntu install instructions, I unfortunately get told there is a missing package.

For me, it looks like this:

@ehammond How could we help here?

[mpdude]

Maybe #107 solves part of the problem?

[mpdude]

While I have almost no experience in maintaining .deb packages and cannot promise I will be able to support this in the long run, for now it might help those coming here:

From the top of the latest project README:

This project is no longer maintained. It is unclear if such a tool is really necessary on EC2/EBS.

1. Modern filesystems and databases have built-in crash recovery, minimizing the importance of "consistent" snapshots.

2. If creating consistent snapshots were a real issue, then surely Amazon would be recommending it in official documentation and would be providing tools to enable it.

3. This project was written in Perl, which has no SDK officially supported by Amazon.

If you are still interested in creating consistent snapshots of file systems using a supported project, you can check out ec2-consistent-snapshot.sh which is inspired by this project and written by one of the former maintainers. It has fewer features and options, but uses the officially supported AWS CLI.

You are also welcome to fork this project and continue working on it under the terms of the "LICENSE".
