As we come to the close of another year, it is a good time to perform some routine tasks on your server, especially if you have been putting them off until “the right time”. The beginning of a new year is usually busy, so you should take the time now to get those tasks done and make sure your server is optimized for the coming year.
One of the most important tasks that you should regularly perform on your server is the backing up of essential data. Every so often, it is also a good idea to check the integrity of your backups. Nothing is worse than actually needing to restore your backups one day and finding out that they do not work or are in some way corrupted.
Your backups are likely stored in compressed archives, so you will need to extract the files from the archives in order to check them. It may be enough to simply verify that the file names and sizes match the files you have. Therefore, it is important to check the latest backup, and that should be sufficient to confirm that the backups are working as expected. If you have any concerns, you can run a more in-depth file system integrity check on the backups.
