Apple Joins The Crowd
开云体育Haven’t you heard of our corporations going all out to help the government without an order to do so!? ? Ford and GM have agreed to convert their auto plants to produce medical devices. Liquor distilleries have agreed to use their plants to make hand sanitizers, I’m expecting a great increase in sales.... Apple has agreed to donate 9 MILLION mask to the government...on it goes.... Free Enterprise at its best. John |
Re: Time Machine
开云体育Well I tried to erase the time machine backup with disk utility and cannot because disk utility cannot unmount the disk. I can erase the other partition with disk utility no problem. I cannot, however, re-partition?the drive to a single partition because disk utility cannot unmount the disk.I purchased the drive at costco in October 2017. I could return it to costco and get a new drive or get my money back but I don't want to do that because the time machine data is still accessible.? Any thoughts?

gmail
Some days I can send email from my gmail address with no problems. Other days, like today and yesterday I get the message: Cannot send message using the server hejb44@... Connection to the server “ on the default ports timed out If I open Safari and connect to gmail that way I have no problem sending the email. Why is this happening and what can I do about it? Thanks. PS it happened again with this message so I am putting it in my drafts folder and then sending it from gmail in safari. |
Re: mac getting sluggish
Pen, may not help at all but I’ve cured many Mac’s, one that was frozen by using Disk Warrior to rebuild the Directory. Might be worth a try.

What I remember is a discussion about optimizing with things like defraggers. Fragmentation is no longer a big problem with SSDs because any block anywhere on the drive can be accessed instantly. The problem I’m worried about with Time Machine is that a long-standing backup might have millions of files in it and many more hard links. All of these have directory entries. HFS+ was not built for such a situation. It is an old file system that dates back to 1998 and was based on HFS dating from 1985 which was largely based on SOS, the Apple III file system for high density floppy disks. Apple introduced APFS because it was becoming clear HFS+ was too clunky to support large drives with millions of files. In the process, they built a lot of modern features into APFS and optimized it for SSDs because it’s clear the days are numbered for spinning rusty platters. Returning to the limitations of HFS+ and Time Machine, I still think hard links are a problem. In all other Unix/Linux file systems you can have more than one directory entry pointing to one file. The additional entries are called hard links. It was impossible to do this with HFS+, so the Apple guys cheated. A hard link in HFS+ is a directory entry for an invisible file on the drive which contains the address of the file they want to link. (In programming lingo it’s a pointer to a pointer.) Since these pointer files are invisible, copying the files you can see to another drive leaves out a lot of information needed by Time Machine. It could be there are utilities for rebuilding the links in another location, but why take the chance? I’d just nuke and pave.

Re: Time Machine
Thanks Lee & John. I’ll keep you posted.

Re: Time Machine
开云体育Lee, If I remember right there was a discussion previously that suggested the newer Apple computers Apple’s SSD’s, ?no longer had to have their directories rebuilt. ?True? ? If so & an SSD TimeMachine is attached would it still have to be rebuilt as needed?? Thanks, John On Mar 23, 2020, at 10:17 PM, Lee Larson via Groups.Io <leelarson@...> wrote:

Re: Time Machine
That should work if there is a separate directory for each partition. I don’t know but I suspect so?

My experience with Time Machine is that this always happens sooner or later. The only fix I’ve found is to nuke the backup and start over. I’ve stated several times before that I don’t trust Time Machine. My reason is because Time Machine is clearly designed to work like a standard Unix/Linux backup utility called rsync. The problem is that rsync depends heavily on another Unix/Linux feature called hard linking. This hard linking is a capability built into Unix/Linux file systems. The Mac’s HFS+ file system had no hard linking, so the Apple elves grafted it on just to make Time Machine work. It’s always been somewhat flakey and my theory is HFS+ seems to get confused when there are too many links in a directory. The new Mac file system, APFS, does do hard linking, so I expect there will soon be an APFS version of Time Machine. I’m just looking at this plague-based house arrest as a rehearsal for my voyage to Mars. |
Re: Time Machine
What if I copy the time machine backups to the larger partition on the hard drive and then reformat the Time Machine partition?

Re: Time Machine
开云体育Harry,?I’ve had almost the identical problem a couple times, but no partition involved. ? The problem in my case was a directory so whacked it quit working. I wasn’t able to rebuild the directory using Disk Warrior because there wasn’t space in the drive for DW to perform it’s task. I had to hold my breath both time that I wouldn’t lose my main drive while I formatted TimeMachine and began a fresh backup, which then lasted for months and months until the directory once again becomes corrupted. I guess to be safe I should attach another TimeMachine drive and backup to it before wiping out the damaged one…one day I may get caught for not being safe. This may not address your question but I thought I would share my experiences. John

Time Machine
Time Machine on my wife’s MacBook Pro hasn’t backed up since March 12. When I tell Time Machine to back up I get this window: When I click on details I get this window: Time Machine backs up to a 1TB partition on a 4TB ssd When I run disk utility on the Time Machine partition I get this message: I can successfully run disk utility on the 3TB partition of the ssd.? Any suggestions? Thanks. |
