Yes, both the quota and the storage itself are shared. Backups and archives are visible to users on all the computers, signed into the same Acronis account (see "Account" tab in the product).

When using a multi-seat license, set a password for your backups to prevent users on other computers under the same Acronis account from accessing the contents of your backups. They will still be able to see the names and overall size of your backups. Password can be set only before the first backup version is created. If you'd like to enable password protection for already existing backup, delete it and then re-create from scratch, setting the password during the initial configuration.

The error does NOT mean that the license is expired, unusable anymore or blocked. This error only tells that a change in hardware has been detected or the limit of computers where Acronis True Image may be used at the same time has been reached. The issue is easily resolved by following instructions in this article.

If you have a serial number for an earlier version of Acronis True Image, insert it as the second key.

If you had Acronis True Image, shipped with the SSD or HDD, or pre-installed on new computer, and then upgraded to the full version of Acronis True Image, make sure that the full version is installed on top of the previous version. If you have removed OEM, HD, Personal or Data Protection edition of Acronis True Image, please uninstall the full version, then install back the OEM, HD, Personal or Data Protection edition, and then install the bought full version over it. The software will detect the upgrade and will not ask for a second key.

Backup will stop working if there will be not enough free disk space in the destination. If you see that the location, where backups are stored, is filled up with Acronis backup files, do the following:

1. Click a small arrow next to the backup in the product interface and choose "Clean up versions" from the backup menu. Delete backup versions to make room for future backups.
   
   Do not delete backups outside of Acronis True Image user interface, otherwise the rest of the backups could become not recoverable! Learn more here.
2. Adjust the automatic backup deletion rule to prevent the destination from filling again:
   1. Click Options in the product interface
   2. Click on the Backup scheme tab
   3. If the cleanup rule is not defined yet, select "Incremental" or "Differential" backup scheme and click "Turn on automatic cleanup"
   4. If the cleanup rule is already defined, reduce the number of days, backup chains to keep or the total allowed backup size.
      1. When it is time to delete a backup, according to the cleanup rule, the actual deletion will happen only when all of dependent incremental and differential backups also satisfy the same cleanup criteria. 
      2. Always plan for one extra full backup, because the automatic cleanup happens after a new full backup is created, not before.

When the disk cloning is performed in running Windows without reboot, disk volumes on the clone are not assigned drive letters, which makes them invisible in Windows Explorer. It is done with the thought in mind, that you disconnect the clone after it is created, and only connect it as a replacement for the original disk. The reason why having two identical disks connected at the same time is not recommended, is because Windows would automatically change the disk signature of one of them to distinguish between them, which may make it unbootable.

If you still need to have both the original and the clone disks connected at the same time, open Start menu, type diskmgmt.msc, press Enter, right-click disk partitions on the clone disk in the opened Disk Management window and choose "Change Drive Letter and Paths...", assign a drive letter. This will make the disk visible in Windows Explorer.

To clone all or selected disks, follow instructions in the User Guide.

Note that cloning just selected disk partitions or disk volumes is not supported. Only an entire disk with all the partitions and volumes can be cloned.

Boot Camp can be cloned only along with all other partitions of the same disk. It cannot be copied/cloned separately.

If you already have a bootable media, then no, Acronis Survival Kit is not necessary. Acronis Survival Kit is the same bootable media and a storage for backups, combined onto the same USB disk device.

If you do not have a bootable media, then the answer is yes, click "Create Acronis Survival Kit" to have the bootable media and backups on a single USB disk.

Acronis Survival Kit is not better or worse than a regular bootable media on CD, DVD or USB stick in terms of functionality and available features.

Learn more about Acronis Survival Kit in the User Guide (Windows, Mac).

If Acronis Universal Restore Media Builder is installed, Linux-based media in Acronis Survival Kit will include Universal Restore, and WinRE/WinPE - will not.

Learn more about Acronis Survival Kit in the User Guide (Windows version). Mac version does not have Acronis Universal Restore.

If you plan migrating to a new computer, needing Acronis Universal Restore, insert a blank CD, DVD or pendrive, launch Acronis True Image, click on Tools - Acronis Universal Restore and write a separate bootable media with Acronis Universal Restore on it.
