(NASDAQ: ARQ) (the “Company” or “Arq”), a producer of activated carbon and other environmentally efficient carbon products for use in purification and sustainable materials, today announced the execution of its first sales contract for delivery of GAC produced from its unique purified bituminous coal waste derived feedstock at its strategic Red River facility.Under the terms of the agreement, the new Arq customer, a North American solutions provider of water and wastewater treatment and PFAS capture technologies, will purchase a forecasted 5 million pounds of GAC product in 2025, reflecting approximately 20% of the facility’s initial expanded nameplate capacity of 25 million pounds per year.Bob Rasmus, CEO of Arq commented, “Today’s announcement reflects a critical milestone in the ongoing strategic transformation of Arq. Our first GAC supply contract represents third party validation of our strategy and our GAC solutions. The contract demonstrates follow through on our commitment to stakeholders and the hard work of our entire team. The contract pricing is attractive, and represents a multiple of our average PAC pricing. This amplifies our confidence in our strategy while further de-risking the strategic development of Red River. We now have approximately 20% of our nameplate Red River capacity now contracted nearly 9 months ahead of commissioning. We remain in advanced levels of dialogue with a range of potential counterparties. Based on those discussions, we remain in an enviable and exciting position to contract the remainder of our capacity prior to initiation of production at attractive rates.”Garrett Chandler, VP Sales of Arq added, “Securing this strategic partner as our first GAC customer is an exciting development as we aim to deliver successfully into a pipeline of sales growth.

You’re still not doing a proper backup or you’re not completely satisfied with Time Machine? Arq Backup should make your life a lot easier.Which Backup Program for Mac? This one.Arq Backup is a very stable program that works wonderfully. What it can’t do: create bootable images. So it only serves to backup your user folder (or other freely configurable sources). In addition, it costs about 50 dollars, lifetime upgrades 30 dollars more. Fair enough: the license is per user, so you can backup iMac, MacBook and Tinker-Mac with Arq. First of all: the price is very fair for the functions and in case of a data loss it’s a gift anyway.What is the difference to other backup programs (of which we have listed some good ones here)? Basically, Arq is specialized in online backups. Of course local folders also work (also on a NAS), but the intended purpose is an online backup. And here comes a serious advantage: Arq encrypts the backups before they leave your computer. So if you’ve always been afraid to make backups in the cloud, you’ve now found a tool that keeps your data private, no matter where they end up (assuming, of course, that you choose a secure and long password).In addition to the local data options, Arq offers compatibility with almost all online services:Amazon DriveAWS (S3 and GlacierBackblaze B2DropboxGoogle DriveGoogle Cloud StorageOneDriveSharePointWasabiall S3 compatible offersAnd for your own projects alsoSFTPSo if you already make a local backup and are looking for a solution to a good online backup, then we can highly recommend Arq to you.Easy to operate, stable and reliable in operation, indispensable in case of doubt.The setup is simple, the design and structure dry and unobtrusive. This is exactly what you expect from a program that you entrust with your data and whose skills usually work in secrecy.To create your backup, enter the appropriate data for your service, add the folder to be backed up (usually your home folder) and let the program do its magic. Restoring the data is similar: You can browse the directory tree by date and select the appropriate folders or files to find your way back to the hard disk.It should not go unmentioned that Arq uses a different format for storing the data, which is independent of the file system of the storage location. This allows Arq to save all metadata of macOS files such as color labels. Many backup programs simply store the files on file system level and then have to mediate between macOS APFS and others. This is not the case with Arq and is another unique feature that makes the program the first choice when it comes to reliably backing up important data.

Script in Terminal:~/Desktop/MountNas.shIt might take a few seconds to complete. If you now type:mountyou should see a line for your NAS.Step 5: Tell Arq to run the script before starting backupPick “Preferences” from Arq’s menu, click the Destinations tab, and double-click your destination.Click the “Before and After Backup” tab.Check “Run shell script before backup starts” and click the Choose button to find and select your MountNas.sh script. Then click Save, and close the Preferences window.Step 6: Add folder(s) from your NAS to ArqYour NAS should still be mounted from Step 4. Pick “Add Folder to Backups” from Arq’s menu to add the folder(s) on the NAS that you want backed up.Step 7: Test the backupGo to the Finder and click the eject button to unmount your NAS.Pick “Back Up Now” from Arq’s menu. Arq will run the script to mount the NAS, and then back up the files you selected. Once the backup is underway, check in the Finder whether your NAS is mounted. If it didn’t mount, then Arq should report an error. If you need help finding the problem, please email us at support@arqbackup.com; we’re always happy to help!NAS Backup on WindowsOn Windows the process is different. In Arq for Windows you can tell supply the parameters for connecting to the NAS and Arq Agent will connect it when it needs to access it.Step 1: Add the NAS in Arq’s preferencesPick “Preferences” from Arq’s menu, click the Network Volumes tab, and click “Add…” to add your NAS.

Data is on the desktop (nearly 2TB), and no laptop has very much on it's internal drive at all, spending $60/laptop/year for a tiny amount of data vs just putting it all in one Amazon Cloud Drive account makes little sense for me.My perhaps only concern is that Arq is a small concern, so what happens if the developer decides to quit? They do have an open sourced command line utility for retrieving data that is hosted on GitHub. I have never tried it. Arq is my "last resort" since I also have 2 TimeMachine drives and 2 daily clones (one on a Drobo) on my desktop, so I'm only going out to Arq if all 4 of those backups die, so as a result, if Arq does disappear one day, I will (hopefully) be OK while I wait for everything to upload to a new cloud service.Hope this info is helpful..

Arq 7 stores your backup data in de-duplicated, compressed, (optionally) encrypted, content-addressable form.A “backup set” is a set of files created by a “backup plan”.It contains: backupconfig.json backupfolders.json backupfolders/ backupplan.json blobpacks/ largeblobpacks/ treepacks/ standardobjects/ standardiaobjects/ onezoneiaobjects/ s3glacierobjects/ s3deeparchiveobjects/backupconfig.jsonThis file tells Arq how objects are to be added to the backup set – whetherthe data are encrypted, what kind of hashing mechanism to use, what maximumsize to use for packing small files together, etc.Here’s a sample backupconfig.json file:{ "blobIdentifierType" : 2, /* 1=SHA1, 2=SHA256 */ "maxPackedItemLength" : 256000, "backupName" : "Back up to NAS", "isWORM" : false, /* unused */ "containsGlacierArchives" : false, "additionalUnpackedBlobDirs" : [], /* if reused Arq 5 data, contains e.g. 'objects', or 'objects2' */ "chunkerVersion" : 3, /* Arq uses the same chunker version to ensure de-duplication works with old data */ "computerName" : "clack", "computerSerial" : "unused", "blobStorageClass" : "STANDARD", /* unused */ "isEncrypted" : false}backupfolders.jsonThis file tells Arq where to find existing objects (for de-duplication).{ "standardObjectDirs" : [ "\/5E7D9CE7-04DA-42E3-B55E-B35D76F29D03\/standardobjects" ], /* only used with S3 */ "standardIAObjectDirs" : [ "\/5E7D9CE7-04DA-42E3-B55E-B35D76F29D03\/standardiaobjects" ], /* only used with S3 */ "onezoneIAObjectDirs" : [ "\/5E7D9CE7-04DA-42E3-B55E-B35D76F29D03\/onezoneiaobjects" ], /* only used with S3 */ "s3GlacierObjectDirs" : [ "\/5E7D9CE7-04DA-42E3-B55E-B35D76F29D03\/s3glacierobjects" ], /* only used with S3 */ "s3DeepArchiveObjectDirs" : [ "\/5E7D9CE7-04DA-42E3-B55E-B35D76F29D03\/s3deeparchiveobjects" ], /* only used with S3 */ "importedFrom" : "5.x" /* only appears if backup set was originally created by Arq 5 */}backupfolders/For each folder specified in the backup plan, at backup time Arq creates a directory in backupfolders with a UUID as its name.Within that directory are a JSON file called ‘backupfolder.json’ describing the directory, and backup records.Here’s an example backupfolder.json file:backupfolders//backupfolder.json{ "localPath" : "\/Users\/stefan", "migratedFromArq60" : false, "storageClass" : "STANDARD", "diskIdentifier" : "ROOT", "uuid" : "F1F83A27-E4EA-4994-BD9C-F63A682EBB80", "migratedFromArq5" : false, "localMountPoint" : "\/", "name" : "stefan"}backupfolders//backuprecords/00161/4294169.backuprecordEach backup record is stored with a name that is the number of seconds since the epoch.For example, 00161/4294169.backuprecord was created Thu Feb 25 18:02:49 2021.The backup record file contains: a copy of the backup plan at the time of backup a Node describing the root of the directory structure stored some additional metadataThe file is stored LZ4-compressed and (optionally) encrypted.Here’s an example:{ archived = 0; arqVersion = "7.3.1.0"; backupFolderUUID = "4297DBE8-DA5E-48EC-A1DB-0CDB47D7EE55"; /* copy of the backup plan at the time of backup: */ backupPlanJSON = { active = 1; arq5UseS3IA = 0; backupFolderPlansByUUID = { "4297DBE8-DA5E-48EC-A1DB-0CDB47D7EE55" = { allDrives = 0; backupFolderUUID = "4297DBE8-DA5E-48EC-A1DB-0CDB47D7EE55"; blobStorageClass

Arq can backup NAS shares. Here’s how to set that up on a Mac. (For Windows skip to the “NAS Backup on Windows” section.)Please note: This article only applies to Arq 5. Arq 6 will take care of mounting the NAS for you.NAS Backup on MacArq will back up whatever folders you tell it to back up, but it doesn’t know where those folders really exist on your Mac. So, if you want to back up, say, a NAS that isn’t always connected, you may need to tell Arq to connect to the NAS first.Step 1: Figure out how the Finder mounts your NASWhen you connect to your NAS to your Mac by browsing to it in the Finder, the Finder takes care of “mounting” the NAS volume for you. To find out how, browse to your NAS volume in the Finder; then open the Terminal app and typemountand press Return. One of the lines in the output will mention your NAS and look something like this://stefan@big._afpovertcp._tcp.local/bignas on /Volumes/bignas (afpfs, nodev, nosuid, mounted by stefan)In my case, my NAS is called “big” and the share on it is called “bignas”. I connected to it with the username “stefan”. The Finder mounted it at /Volumes/bignas. The “afpfs” tag means the Finder mounted it using AFP; if you see “smbfs” instead, it means the Finder mounted it using SMB.To recap, the key items in that line are:“stefan” -> the account name used to connect to the NAS device“big” -> the name of.

We now have approximately 20% of our nameplate Red River capacity now contracted nearly 9 months ahead of commissioning. We remain in advanced levels of dialogue with a range of potential counterparties. Based on those discussions, we remain in an enviable and exciting position to contract the remainder of our capacity prior to initiation of production at attractive rates.”Garrett Chandler, VP Sales of Arq added, “Securing this strategic partner as our first GAC customer is an exciting development as we aim to deliver successfully into a pipeline of sales growth.

You’re still not doing a proper backup or you’re not completely satisfied with Time Machine? Arq Backup should make your life a lot easier.Which Backup Program for Mac? This one.Arq Backup is a very stable program that works wonderfully. What it can’t do: create bootable images. So it only serves to backup your user folder (or other freely configurable sources). In addition, it costs about 50 dollars, lifetime upgrades 30 dollars more. Fair enough: the license is per user, so you can backup iMac, MacBook and Tinker-Mac with Arq. First of all: the price is very fair for the functions and in case of a data loss it’s a gift anyway.What is the difference to other backup programs (of which we have listed some good ones here)? Basically, Arq is specialized in online backups. Of course local folders also work (also on a NAS), but the intended purpose is an online backup. And here comes a serious advantage: Arq encrypts the backups before they leave your computer. So if you’ve always been afraid to make backups in the cloud, you’ve now found a tool that keeps your data private, no matter where they end up (assuming, of course, that you choose a secure and long password).In addition to the local data options, Arq offers compatibility with almost all online services:Amazon DriveAWS (S3 and GlacierBackblaze B2DropboxGoogle DriveGoogle Cloud StorageOneDriveSharePointWasabiall S3 compatible offersAnd for your own projects alsoSFTPSo if you already make a local backup and are looking for a solution to a good online backup, then we can highly recommend Arq to you.Easy to operate, stable and reliable in operation, indispensable in case of doubt.The setup is simple, the design and structure dry and unobtrusive. This is exactly what you expect from a program that you entrust with your data and whose skills usually work in secrecy.To create your backup, enter the appropriate data for your service, add the folder to be backed up (usually your home folder) and let the program do its magic. Restoring the data is similar: You can browse the directory tree by date and select the appropriate folders or files to find your way back to the hard disk.It should not go unmentioned that Arq uses a different format for storing the data, which is independent of the file system of the storage location. This allows Arq to save all metadata of macOS files such as color labels. Many backup programs simply store the files on file system level and then have to mediate between macOS APFS and others. This is not the case with Arq and is another unique feature that makes the program the first choice when it comes to reliably backing up important data.
