It’s the go-to all-in-one system maintenance software to breeze through cleanup and wipe out all types of clutter. PowerMyMac is a safe pair of hands and a preventative measure to free up purgeable storage space on your Mac. iCloud’s 5GB storage space will be filled to the brim quickly if you allow junk files to claim gigabytes of room. You only need to run regular scans and farm out all types of redundant content. It zeroes in on system junk like broken links, cache files, and vestiges of uninstalled apps. iMyMac PowerMyMac offers thoroughbred cleanup and optimization tools to keep clutter at bay. Unlike Time Machine, cloud services garbage down junk files and eat up precious space. PowerMyMac-The Must-Have Instrument for Cleanup Accordingly, this nomenclature rules out cache files, log files, junk, and certain app settings. So, what does Time Machine backup? Contrary to the popular opinion that Time Machine backs up everything, it excludes a variety of files based on ecosystem rules. Restore everything, reinstall macOS and then load on everything with Time Machine. In case you inadvertently remove your recovery partition and you want to restore it back, you need to regenerate it and understand what does Time Machine backup. It also allows you to delete snapshots without banishing data associated with other backups. The hard-link system benefits include intuitive navigation via Finder, and also a simple approach of reinstating a snapshot even without extra operations. They’re removable without purging the original until you remain with one link. Each instance of the file presents a link to that one special version. The hard link keeps the file extent uniquely once on a drive. Time Machine uses a hard link that mimics and behaves like a separate clone of a file accessible via the Finder or Terminal.

Does time machine backup photos or anything? At the outset, Time Machine does not back up everything, unlike duplication-centered solutions like MacDaddy.Ĭontents: Part 1. It only duplicates a file if altered, but this generates snapshots for every backup with hard links for each item on the backed-up drive.īut the stark contrast with proprietary backup tools is that it not only mothballs spare duplicates of all files but also memorizes how your Mac looked on any day so you can walk back in time. Time Machine runs like clockwork without manual upkeep or fuss. It’s designed for archival.Time Machine uses a unique method that mimics complete backups after creating a copy for modified files at hourly intervals. To protect your data - configure any of the existing first or third party solutions - cloudstation, duplicacy, Arq, cloudberry, whatever you like - and use 2 destinations for them - synology box and cloud storage, such as B2 or Wasabi.īecause you will only be backing up changes in user data you can keep a very long history at very low cost.įor the Glacier - it is not designed for backup. It shall never be your only or primary backup. I’d argue you don’t care about history of system files but you do want long history of your user files. Which means OS update will result in purging of some of the user files history. See, with time machine both user file and system file changes compete for the space in the backup store. In a time machine only last state really matters. It was designed to maintain local system backup so that if you lose your Mac you can restore everything to a new one. Time machine was not designed for remote operation. You should not backup your backup of your data offsite you shall backup your data itself instead. Time machine is a versioned backup of your data. However, entire exercise is utterly pointless to begin with. You can make it more robust by taking a filesystem snapshot when time machine is not running (btw, it’s not trivial to determine when is that) and then copy the bundle from the snapshot. It’s state is only ever coherent when it is unmounted - in the mounted sole systems there is data that has not been flushed yet and therefore if you do copy the image state as-is you will end up with corrupted and unusable copy. Sparse bundle is just a set of small-ish files (bands) and their collection makes a mountable filesystem. You will need to ensure that the bundle is unmounted during copy, I.e. It’s all about effort/reward and using the right tools for the job - which makes it easier and more reliable.
