Hi Alexander tested the diff command with version v0.Both are often used as chemical checklists to support product safety and chemical management activities.

Both lists can contain similar chemicals, and both are used for testing materials and products, but there are distinct differences between RSL and MRSL, which are explained in this article below. MRSL stands for Manufacturing Restricted Substance List and provides brands, retailers, suppliers and manufacturers with acceptable limits of restricted substances in chemical formulations which are used in the raw material and product manufacturing processes.

An MRSL is used as a tool by companies around the world to regulate the safety of chemical formulations used to make the raw materials that go into products and samples.

The regulation of chemical formulations upstream, through an MRSL, protects workers, consumers and the environment. Adhering to an MRSL can also protect brands and retailers from any potential negative publicity on product safety. But, does your company know whether the MRSL is being adhered to effectively by suppliers further upstream? MRSL testing analyses the chemical formulations which are used to manufacture raw materials that go into the production of consumer goods.

MRSL testing identifies the amount of each restricted substance on the MRSL that is present in a single chemical formulation, and there are often several chemical formulations that are used to manufacture raw materials which in turn, need to be tested to the acceptable limits on the MRSL. BLC goes one step further and not only offers MRSL testing, but also offers advanced technical support when failures occur, providing your business with solutions.

RSL stands for Restricted Substances List and is often used as a chemical checklist when testing finished products for the presence of restricted substances. An RSL does not have any involvement with the manufacturing process and only applies to finished articles.

This article demonstrates how to automate backups with restic using only systemd unit files. For an introduction to restic, be sure to check out our article Use restic on Fedora for encrypted backups.

Then read on for more details. Two systemd services are required to run in order to automate taking snapshots and keeping data pruned. The first service runs the backup command needs to be run on a regular frequency.

Automate backups with restic and systemd

The second service takes care of data pruning. Check out the series on systemd here at the Magazinestarting with this primer on unit files:. To install use this command with sudo :. Copy and paste the text below into the file for best results. Copy and paste the content below for best results.

This example uses BackBlaze B2 buckets. Adjust the ID, key, repository, and password values accordingly. Now that the service is installed, reload systemd: systemctl —user daemon-reload. Try running the service manually to create a backup: systemctl —user start restic-backup. Because the service is a oneshotit will run once and exit. After verifying that the service runs and creates snapshots as desired, set up a timer to run this service regularly.

For example, to run the restic-backup. Again, copy and paste this text:. While the main service runs the forget command to only keep snapshots within the keep policy, the data is not actually removed from the restic repository.

The prune command inspects the repository and current snapshots, and deletes any data not associated with a snapshot. Because prune can be a time-consuming process, it is not necessary to run every time a backup is run.

This is the perfect scenario for a second service and timer. Similarly to the main restic-backup. Yes, this appears to be a formatting error with the HTML. WordPress renders it as two dashes, but when viewing the post itself, the two dashes appear to be squashed together into an emdash. Since all the unit files are installed as the running user, you must interact with the user systemd session. You do not need to run this as root.

So you should interact with systemd as your normal user via the —user flag. Thank you it workssomehow for learning what would be the changes in restic-backup. Better how? Both duplicity and Restic supports backup encryption and backing up to multiple cloud providers as well as local and networked backup destinations.

Restic lets you deduplicate data from multiple systems in a single backup repository.Run the following command and enter the repository password you chose above again:. As you can see, restic created a backup of the directory and was pretty fast! The specific snapshot just created is identified by a sequence of hexadecimal characters, 40dc in this case. You can see that restic tells us it processed 1.

It also tells us that only 1. This means that some of the data was duplicate and restic was able to efficiently reduce it. Be aware that the live status shows the processed files and not the transferred data.

Transferred volume might be lower due to de-duplication or higher. This is de-duplication at work!

You can even backup individual files in the same repository not passing --verbose means less output :. In fact several hosts may use the same repository to backup directories and files leading to a greater de-duplication. When you backup the same directory again maybe with new or changed files restic will find the old snapshot in the repo and by default only reads those files that are new or have been modified since the last snapshot. This is decided based on the following attributes of the file in the file system:.

Now is a good time to run restic check to verify that all data is properly stored in the repository. You should run this command regularly to make sure the internal structure of the repository is free of errors.

You can exclude folders and files by specifying exclude patterns, currently the exclude options are:. Please see restic help backup for more specific information about each exclude option. Patterns use filepath. Glob internally, see filepath. Match for syntax. Environment-variables in exclude files are expanded with os. Patterns need to match on complete path components.

For example, the pattern foo :. Spaces in patterns listed in an exclude file can be specified verbatim. That is, in order to exclude a file named foo bar star.

Please note that beginning and trailing spaces are trimmed - in order to match these, use e. Spaces in patterns listed in the other exclude options e. By specifying the option --one-file-system you can instruct restic to only backup files from the file systems the initially specified files or directories reside on. By using the --files-from option you can read the files you want to back up from one or more files. This is especially useful if a lot of files have to be backed up that are not in the same folder or are maybe pre-filtered by other software.

Incidentally you can also combine --files-from with the normal files args:. Paths in the listing file can be absolute or relative. Please note that patterns listed in a --files-from file are treated the same way as exclude patterns are, which means that beginning and trailing spaces are trimmed and special characters must be escaped.

Do you have any idea what may have caused this? Integer overflow?Nicolas had no way of even accessing his data, turning the inconvenient but trivial task of migrating servers into a potentially fatal situation for his company. How DigitalOcean just killed our company raisupcom. A long thread for a very sad story. Predictably, there were a lot of Monday - morning quarterbacks who weighed in, scolding him for not having backups he didbut they were also stored on DigitalOcean and not paying a boatload of non-existent money for expensive load balancers pointing to multiple cloud providers.

Most of the popular one-click server providers including DigitalOceanas well as LinodeVultrand OVH provide their own backup offerings for an additional monthly cost usually proportional to your plan.

But as Nicolas learned the hard way, any amount of backups are just more eggs in the same basket if everything is under one account with one credit card on one provider. The following steps are how I backup my various VPSes to a totally separate cloud in the sky. There are quite a few tools that have been around for decades that could accomplish this task — namely rsync — but an open-source tool named Restic has won my heart for both its simplicity and the wide range of destinations it natively supports, including but not limited to:.

Setting up Restic is certainly easier than a low-level tool like rsyncbut it can still be tricky. Find the latest version of Restic on their GitHub releases page. This should leave us with a single file: the Restic binary. This step is a little different for each cloud provider. You can generate a super-secure character password by running openssl rand -base64 32 — just make sure you store it somewhere safe! This saves a config file in your S3 bucket and starts the encryption process right off the bat.

You only need to run this once. If successful, you should see a message containing created restic backend. If not, make sure you set all four environment variables correctly and try again. All we need to specify is the directory you want to backup. You should see one listed at this point if everything went according to plan. Thankfully, Linux makes it incredibly easy to automate scripts using cron jobs.

Make a new file at a convenient location on your server and name it backup. Using forgetwe can specify how many snapshots we want to keep and from when. This command keeps one snapshot from each of the last six hoursone snapshot from each of the last seven daysone snapshot from each of the last four weeksand one snapshot from each of the last twelve months. Reading the documentation for different forget options can be helpful if you want to customize these. Save the shell script and close the editor.

Lastly, we need to set the actual cron job. To do this, run sudo crontab -e and add the following line to the end:. The first part specifies how often the script should run.

The second part specifies where the script we just wrote is located, of course, so set that to wherever you saved backup. Side note: In order to use restic in future shell sessions, we need to make the four environment variables permanent by adding them to your.

Simply copy and paste the four export lines from the backup. Take note of the next time that your new cron job should run, so we can check that it was automatically triggered. To restore a snapshot to a certain location, grab the ID from restic snapshots and use restore like so:. There are a few other neat options for browsing and restoring snapshots, like mount ing a snapshot as a disk on your file system.

If you have any questions, feel free to leave a comment or get in touch with me. Be safe out there! June 9, — Improve This Post.Similar to programs such as gitrestic has a number of sub-commands. You can see these commands in the listing above. Each sub-command may have own command-line options, and there is a help option for each command which lists them, e. Subcommand that support showing progress information such as backupcheck and prune will do so unless the quiet flag -q or --quiet is set.

Comparing Snapshots with Restic

When running from a non-interactive console progress reporting will be limited to once every 10 seconds to not fill your logs. Use backup with the quiet flag -q or --quiet to skip the initial scan of the source directory, this may shorten the backup time needed for large directories. Additionally on Unix systems if restic receives a SIGUSR1 signal the current progress will be written to the standard output so you can check up on the status at will.

Managing tags on snapshots is done with the tag command.

The existing set of tags can be replaced completely, tags can be added or removed. The result is directly visible in the snapshots command.

Note the snapshot ID has changed, so between each change we need to look up the new ID of the snapshot. But there is an even better way, the tag command accepts --tag for a filter, so we can filter snapshots based on the tag we just added.

Internally, a repository stores data of several different types described in the design documentation. You can list objects such as blobs, packs, index, snapshots, keys or locks with the following command:. The find command searches for a given pattern in the repository. The cat command allows you to display the JSON representation of the objects or their raw content.

Restic saves and restores most default attributes, including extended attributes like ACLs. Use the stats command to count up stats about the data in the repository. There are different counting modes available using the --mode flag, depending on what you want to calculate. The default is the restore size, or the size required to restore the files:.

For example, to calculate how much space would be required to restore the latest snapshot from any host that made it :. If multiple hosts are backing up to the repository, the latest snapshot may not be the one you want.

You can specify the latest snapshot from only a specific host by using the --host flag:. But how much space does that snapshot take on disk? We can check:. Comparing this size to the previous command, we see that restic has saved about 23 GiB of space with deduplication. Which mode you use depends on your exact use case. The following example lists all snapshots as JSON and uses jq to pretty-print the result:. During some operations e.

Restic keeps a cache with some files from the repository on the local machine. This allows faster operations, since meta data does not need to be loaded from a remote repository.

The cache is automatically created, usually in an OS-specific cache folder:. The parameter --no-cache disables the cache entirely.
