If you have caps or throttles on your broadband data upload, Time Machine backups can easily push you over, too, for this reason. However, CrashPlan’s archive grew to 303.5GB. Over a week, that Mac’s Time Machine backup reached 63GB. (This also makes it difficult to copy a Time Machine backup from one volume to another without bloating the size.)Ĭode42 tested how quickly Time Machine archives grew with a 53GB volume on a Mac. If you back up files from that volume using file-based archiving software, hard links are copied each time they appear. It’s clever, but it only works within a single volume. These hard links can appear multiple times in a volume, but all refer to a single file. That omits making a fresh copy of any file that remains the same between those bakcups. The primary issue is that Time Machine uses a special kind of alias, called a hard link, to create complete snapshots for each point in time that a backup operation happens. The scripts only deal with the high level things like authentication, configuring, etc (all using the REST API) while the uploads and downloads are deferred to the command line program (the scripts can do upload/download with the REST API as well if hey can't find the binary).The issue with Time Machine and onlne backup
Besides the perl scripts, there is a pre-compiled binary command line utility to deal with high-efficiency data transfers. Their code is a complete mess and I started making a Python replacement before finding rclone for all my other data-movement needs. I have somewhat studied their perl scripts for idrive-backup (which may also be used for idrive-sync). I am curious if either the idrive-backup or idrive-sync support S3 as well. - enterprise storage, 2TB is $70/year with discouraged egress, 30-day free trial, definitely supports S3.Supports WebDAV but is significantly limited.
- for syncing, there is free (5GB) and then higher levels (150GB-1TB, $35-$300/year), much more expensive, presumably since this is designed for high egress unlike the backup one.- for backup, the free (5GB) and personal levels (5TB, $70/year) don't support WebDAV as mentioned above, higher levels may (although I cannot confirm).
They support S3 as well, see the following resources:Ĭonfusing the matter there seem to be several separate services under similar names:
