Arq 5: Massively faster backup and restore - 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

Backup shared libraries? Yes. #13 Why limit the backup to photos only? IMO you could have a bigger customer base if you had a generic tool for offsite backups of all your important data. Something like Arq but hopefully faster. #14 Why limit the backup to photos only? IMO you could have a bigger customer base if you had a generic tool for offsite backups of all your important data. Something like Arq but hopefully faster. I'm a solo developer and have to limit my scope to what is feasible. Backing up my large iCloud photo library was a personal pain point for me, and based on the comments of others here it seems like I'm not alone. There are already many other generic backup tools including Apple's own Time Machine. #15 Why limit the backup to photos only? IMO you could have a bigger customer base if you had a generic tool for offsite backups of all your important data. Something like Arq but hopefully faster. I'm not sure about speed, but you may want to look at ChronoSync for that.Though that (just like Time Machine) will backup your file structure, including Photo's proprietary library format (and any associated data base corruption in that), not... a folder structure with the format YYYY/MM/DD for all the photos and videos. That is, as I understand, the appeal raison d'être for this app:A simple, bullet-proof folder structure that can easily be accessed with any potato of a PC.Even after 10 or 20. Arq Backup 5 by Arq.

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.
