Store News Home > Backup & Recovery > Arq for Mac 6.2.30 A complete online backup solution Rating: Operating Systems: Windows 10, Windows 7 (32 bit), Windows 7 (64 bit), Windows 8 License: Trial Software Developer: Haystack SoftwareSoftware Cost: Category Backup & RecoveryDate Updated: 05 June 2020 Downloads To Date: 784 Languages: English Download Size: 27.70 MB Arq is an easy-to-use cloud backup tool which can save your chosen folders to Dropbox, OneDrive, Google Drive/ Nearline, Amazon S3/ Glacier.The program is very straightforward. Once launched, just select your backup destination or destinations (you can use more than one service in the same job) and it automatically backs up your user profile folder. You can select any other folders to protect in a click or two.Your backups will be visible from any other device which can access the same service, and Arq also has a Restore pane of its own, where you can select and recover whatever you need (including previous versions of modified files).While this sounds and looks basic, edit your backup job or check the Arq preferences and you'll find some useful options. For example, a flexible scheduler can run backups every X hours, daily or on demand, as well as pausing backups between the hours you specify. There are also options to limit the total size of your backup, to throttle bandwidth use automatically (slow down uploads when other processes are using the network), and to send email alerts when backups finish or have errors. Verdict: An easy-to-use cloud backup tool with some powerful options and settings.

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.

(in the blobpacks or largeblobpacks subdirectory) or as a standalone file in the “standardobjects” (or“standardiaobjects” etc depending on the storage location type and storageclass chosen).A “blob” is LZ4-compressed, and optionally encrypted.BlobLocA “BlobLoc” is a simple structure that specifies the location and length of a Blob.The “compressionType” value is always 2 (LZ4) for new data.For data reused from Arq 5, the value could be 0 (none) or 1 (Gzip).The “stretchEncryptionKey” value is always 1 for new data.For very old data reused from previous versions of Arq, this value could be 0.Encrypted ObjectAny Backup Record, Tree, Node or Blob that’s encrypted has the following format:header 41 52 51 4f ARQOHMACSHA256 xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xxmaster IV xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xxencrypted data IV + session key xx xx xx xx (64 bytes) ...ciphertext xx xx xx xx ...To create an EncryptedObject: Generate a random 256-bit session key (Arq reuses it for up to 256 objects before replacing it). Generate a random “data IV”. Encrypt plaintext with AES/CBC and PKCS7 padding using session key and data IV. Generate a random “master IV”. Encrypt (data IV + session key) with AES/CBC using the first “master key” from the encryptedkeyset.dat file (see below)and the “master IV”. Calculate HMAC-SHA256 of (master IV + “encrypted data IV + session key” + ciphertext) using the second 256-bit “master key”. Assemble the data in the format shown above.To get the plaintext: Calculate HMAC-SHA256 of (master IV + “encrypted data IV + session key” + ciphertext) and verify against HMAC-SHA256 in the file using the second “master key” from the encryptedkeyset.dat file. Ensure the calculated HMAC-SHA256 matches the value in the object header. Decrypt “encrypted data IV + session key” using the first “master key” from the encryptedkeyset.dat file and the “master IV”. Decrypt the ciphertext using the session key and data IV.encryptedkeyset.dat fileThis file contains keys for encrypting/decrypting and for creating object identifiers.It is encrypted with the encryption password you chose when you created the backup plan.If you later modified the encryption password for the backup plan, Arq rewrote encryptedkeyset.dat encrypted with that new password.The plaintext format (not stored anywhere) is:encryption version 00 00 00 03encryption key length 00 00 00.

Immutable Backups with Arq 7 - Arq Backup Blog

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

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.
